icnss2: Avoid race between SOC WAKE REQ/RESP

There is a race between soc wake release in event queue
and soc wake request called from driver. Due to which
ref count is not updated properly and results in number
of soc wake release send to FW is more than number of
soc wake request. Fix it by atomically incrementing
ref count.
