qcacld-3.0: Remove obsolete "num rx antenna" configuration

Currently cfg.ini supports a "gNumRxAnt" configuration item, and this
is used to override the WNI_CFG_CURRENT_RX_ANTENNA entry in the MAC
CFG database.  However this MAC CFG database entry is no longer in
use, so remove the obsolete support for this configuration item.
