mwifiex: more_task flag for main_process
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.
3. Now work from step1 is scheduled but at first check itself it sees
mwifiex_processing is set and exits.
4. Now if superloop from step2 has passed TX processing part of superloop
this packet would remain in queue until next packet/command/SDIO interrupt
arrives and queues main_work.
This patch fixes this corner case by defining more_task flag which is set when
mwifiex_processing is found to be true. At end of superloop we again check if
more_task flag is set and if set, execute superloop again.
