qcacmn: get sw_exception from reo dest ring descriptor

sw_exception bit will be marked in reo dest ring descriptor for
FW re-injected frame, get this bit and save it in skb->cb,
this bit value can be used for FISA further check.
there is no reo_dest_indication field in reo dest ring on beryllium,
so share same cb member for sw_exception and reo_dest_indication.
