This patch handles a corner case where TX packet would remain in
driver queue till next packet comes in.
Here is sequence:
1. TX packet is queued via hard_start_xmit and main_work is queued
2. SDIO interrupt comes in which directly call mwifiex_main_process.
This starts executing main superloop.
This patch fixes a crash which was happening because of RX of
management frames on uninitialzed interface. Now we drop management
frames for interfaces where cfg80211 has not registered any management
