qcacld-3.0: Fix check for peer_num in wma_get_ll_stats_ext_buf

The current check for peer_num in wma_get_ll_stats_ext_buf is
incorrect and subtracts total_peer_len from WMI_SVC_MSG_MAX_SIZE
and then divides it by the size of peer stats struct.

Fix the check in such a way that peer num is not greater than
WMI_SVC_MSG_MAX_SIZE divided by the sum of total_peer_len
and size of peer stats struct.
