qcacld-3.0: Initialize sap max number of peers

Currently callers are calling the wlan_mlme_get_sap_max_peers() API
to get the max number of peers without initializing the output
parameter.
In case of failure in wlan_mlme_get_sap_max_peers() API,
sap_max_num_peers can have uninitialized value which can lead to
undefined behavior.

To fix this issue, initialize the output parameter before calling
wlan_mlme_get_sap_max_peers()
