qcacld-3.0: Fix OOB in wma_scan_roam.c

Currently in wma_extscan_hotlist_match_event_handler
API, dest_hotlist get memory allocation based on numap
which takes value from event->total_entries.
But numap is limited to WMA_EXTSCAN_MAX_HOTLIST_ENTRIES
and event->total_entries more than WMA_EXTSCAN_MAX_HOTLIST_ENTRIES
can cause out of bound issue.

Fix is to populate dest_hotlist->numOfAps from numap
instead of event->total_entries to avoid any out of bound issue.
