In this handler LOW_RSSI and HIGH_RSSI events are subscribed
to FW using provided threshold value so that FW will monitor
connection quality and trigger any of these events.

Driver will notify cfg80211 about connection quality based on
inputs from FW and provided hysteresis.

1) The wrapper function mwifiex_get_signal_info() is unnecessary.
2) As noise and signal vaules in private structure already get
modified, we don't need to explicitly pass
"struct mwifiex_ds_get_signal" to get it filled.

Earlier we were using dtim period extracted from scan response
buffer provided by FW in scan operation. But it is observed that
sometimes the buffer doesn't contain dtim period tlv, and wrong
value (0) was sent to user space.

After association FW will start listening to beacon frames of
connected AP and store dtim period. Therefore we can get it from
FW in dump_station() instead of using wrong value obtained in
scanning.

Redundant code after adapting new approach for dtim period is
also removed in this patch.

Prior to a5ffddb7 "mwifiex: remove casts of void pointers" the
code assumed that the data_buf parameter could be a NULL pointer.
The patch preserved some NULL checks but not consistently, so there
was a potential for NULL dereferences and it changed the behavior.
This patch restores the original behavior.

In some cases local pointers are used to cast void pointers passed to
the function. Those unnecessary local pointers are also removed.

This patch was inspired by Joe Perches' patch

2) avoid dynamic allocation of wait queue
3) remove unnecessary mwifiex_error_code macros that
were used mainly by the wait queue status code
4) remove some abstraction functions
5) split mwifiex_prepare_cmd() to mwifiex_send_cmd_async()
and mwifiex_send_sync() to handle asynchronous and
