"Flush" request can come from two different sources, it can either from
mac80211, or from device when the operation is needed. Here
adding the support for device issue "flush" request.

When receive tx complete with status is TX_STATUS_FAIL_RFKILL_FLUSH,
issue REPLY_TXFIFO_FLUSH command to uCode to flush out all the tx frames
in queues.

In this condition, since mac80211 has no knowledge of "flush" operation,
driver need to stop all the tx queues and wait for the operation
completed before wake up the queues for frames transmission.

Adding flush callback support in the driver. Two type of flush can be
issued by mac80211:
1. drop = true: frame drop is ok, issue REPLY_TXFIFO_FLUSH host command
to uCode to drop all the frames in tx fifo queues; then return the
control back to mac80211
2. drop = false: wait for either all the frames in tx fifo queues been
transmitted, or timeout; then return the control back to mac80211

If the flush request coming from mac80211, mac80211 will make sure there
are no additional frames push down to driver before flush operation is
completed.

Currently iwlwifi will eventually exhaust the station
table when adding the BSSID station for IBSS mode,
unless the interface is set down.

The new mac80211 ibss joined/left notification allows
us to fix that easily by moving the code to add the
IBSS station to the notification, and also adding
code to remove it again when we leave the IBSS.

We used to free all the Tx queues memory when interface is brought
down and reallocate them again in interface up. This requires
order-4 allocation for txq->cmd[]. In situations like s2ram, this
usually leads to allocation failure in the memory subsystem. The
patch fixed this problem by allocating the Tx queues memory only at
the first time. Later iwl_down/iwl_up only initialize but don't
free and reallocate them. The memory is freed at the device removal
time. BTW, we have already done this for the Rx queue.
