ath6kl: Check wow state before sending control and data pkt
Below two scenarios are taken care in this patch which helped
to fix the firmware crash during wow suspend/resume.
* TX operation (ctrl tx and data tx) has to be controlled based
on suspend state. i.e, with respect to WOW mode, control packets
are allowed to send from the host until the suspend state goes
ATH6KL_STATE_WOW and the data packets are allowed until WOW
suspend operation starts.
* Similarly, wow resume is NOT allowed if WOW suspend is in progress.
