qcacmn: Trigger sys wakeup for WMI command when WOW is enabled

Browse Source 
DHCP packet is received in the IPA exception path when
system is suspending. As part of DHCP packet processing,
WMI_PEER_SET_PARAM_CMDID is sent to FW after WOW is
enabled resulting in self recovery getting triggered by
host.

Fix is to do an explicit system wakeup if a WMI command
has to be sent post WOW enablement.
