wlan: Fix Race Condition in WDA_TxPacket.

In WDA_TxPacket(VosMCThread) in case of Tx timeout, 1st callback
is set as null and then flag is set as timeout. While in
WDA_TxComplete(VosTXThread), 1st it check whether flag is timedout
and then it checks for callback to free Vos Pkt. Hence a race
condition arises whereby Vos Pkt can never be free.
As a prt of fix made sure that in both thread condition check is
in same order.
