Subject: [PATCH] qcacld-3.0: Add dummy event handler function for
 WMI_PHYERR_EVENTID

Currently there are no phyerror event handler either in cmn or cld code,
idea was to implement all DFS code in cmn code. Before enabling event
handler in cmn code need more testing on all the platform which are using
cmn project to make sure not to break radar detection. Until then add dummy
phyerror event handler in cld project. This is mainly to prevent crash due
to watchdog bark because of unhandled event console logs.
