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

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.
