qcacld-3.0: Handle WMI_ROAM_EVENTID with deauth/disassoc reason

Browse source 
When AP sends deauthentication/disassociation frame, host will
handle the deauth/disassoc frame. If the ini
"enable_disconnect_roam_offload" is enabled, firmware will
trigger a roam scan immediately after deauth/disassoc is
received and roam to a new AP. If roam failure happens after
this roam scan, firmware will send  WMI_ROAM_EVENTID with reason
WMI_ROAM_REASON_DEAUTH.

Register a WMA callback to call the PE disconnect handler
function. This will call lim_tear_down_link_with_ap() to
handle the deauth state machine changes and posts message to
sme to inform the link lost info.
