qcacld-3.0: Fix invalid check in softap API

Some of softap APIs like hdd_softap_register_sta() contain sta_id
validation check against maximum value of HDD_MAX_ADAPTERS before
accessing adapter->sta_info[sta_id].

Since the maximum size of adapter->sta_info[] is WLAN_MAX_STA_COUNT
and less than HDD_MAX_ADAPTERS (used in sta_id index validation)
array out of bounds access is possible.

To fix this, validate sta_id index against maximum value of
WLAN_MAX_STA_COUNT instead of HDD_MAX_ADAPTERS.
