qcacld-3.0: Reset fw_peer_count for HO failure during del BSS

Currently fw_peer_count for HO failure is done in wma_roam_ho_fail_handler
which can lead to improper reset of the fw_peer_count if a HDD triggered
disassoc is in progress for the same peer leading to fw_peer_count going
to -1.

Reset the fw_peer_count for HO failure case in wma_delete_bss_ho_fail
API as this is called from the CSR/LIM for handling HO failure as
part of CSR disconnect.
