Subject: [PATCH] qcacld-3.0: Make WMI_ROAM_PMKID_REQUEST_EVENTID event as
 wakable

Add support to make event WMI_ROAM_PMKID_REQUEST_EVENTID as
wakable in FIPS case.
In FIPS Enabled case, for roaming Firmware sends PMKID request
to host as firmware is not supposed to do crypto functionality
with FIPS enabled.
