qcacld-3.0: Fix FW crash caused by lack of rx reorder buffer

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

In high latency, Firmware will trigger crash when no more reorder buffer
left. The number of prealloc reorder buffers depend on tid number, which
equals 4 * clients number, so reassign num_tids in wmi_resource_config to
4 * no_of_peers_supported as Firmware suggested.
