qcacmn: Set the initial wake flag on MSI resume

When the wlan driver is suspending, the last thing it does is check to
see if the firmware has indicated a wakeup during the suspend process.
This is done by checking the initial wakeup flag, which is set when a
specific copy engine payload is received from firmware. For the new
dedicated wake MSI, only the wake signal is received, no payload. When
the wake MSI is toggled, set the initial wakeup flag to prevent race
conditions during the suspend process.
