Currently global wait condition (adapter->cmd_wait_q.condition) is used while sending synchronous commands to FW. When two threads enter in mwifiex_send_cmd_sync() routine at the same time, both the threads wait for their command responses. Since wait condition is same for both, they wake up simultaneously after getting response of 1st command. After this when a thread is waiting for command response of 3rd command, it wakes up after getting response of 2nd command and so on. Therefore we don't wait for the response of last command(0xaa) during unload. Hence while next time loading the driver command time out is seen for INIT command. This problem is resolved by having separate wait condition flag for each command(except scan command). Since scan command is treated differently (by maintaining scan pending q etc.), newly defined flag (scan_wait_q_woken) is used as a scan wait condition.
