Marvell folks tell me this is a debugging event that the driver doesn't
need to handle, but on 8997 w/ firmware 16.68.1.p97, I see several of
these sorts of messages at (for instance) boot time:

[   13.825848] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63
[   14.838561] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63
[   14.850397] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63
[   32.529923] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63

Let's handle this "event" with a much lower verbosity.

Since commit de3bb771 ("cfg80211: add more warnings for inconsistent
ops") the wireless core warns if a driver implements a cfg80211 callback
but doesn't implements the inverse operation.

The mwifiex driver defines a .set_antenna handler but not a .get_antenna
so this not only makes the core to print a warning when creating a new
wiphy but also the antenna isn't reported to user-space apps such as iw.

This patch queries the antenna to the firmware so is properly reported to
user-space. With this patch, the wireless core does not warn anymore and:

Same chip is being used by WLAN as well as bluetooth
drivers. Each driver needs to check during initialisation
if firmware is already active or it needs to be freshly
downloaded. If one driver has started downloading the
firmware, other finds the winner flag as false.

mwifiex_check_fw_status() checks firmware status and also
check if WLAN is the winner for firmware downloading.

Once we detect that other interface is downloading
the firmware, we call this routine again with max
poll count to wait until firmware is ready.

This patch splits the routine to avoid checking
winner status unnecessarily multiple times and ensures
that correct messages are displayed to user.

Firmware status poll count is also increased to 150.

CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
case it already started or starts processing the cmd.
But this was probably not working the way intended:
- it is racy: mwifiex_process_cmdresp might already have passed that
  test and is continuing to use the cmd node being recycled
- mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
  we just set to NULL
- mwifiex_recycle_cmd_node will clear the flag

The reason why it probably works is that mwifiex_cancel_pending_ioctl
is only called from mwifiex_cmd_timeout_func, where the there is little
chance of a command response still arriving
