qcacld-3.0: Fix Kconfig entry for MCC to SCC switch/LFR subnet detection

Correct the Kconfig entry that is used for the MCC to SCC switch and LFR
subnet detection feature. The Kconfig, instead of having the config name
is having the feature name. i.e, instead of having the Kconfig entries
as MCC_TO_SCC_SWITCH and LFR_SUBNET_DETECTION, the current entries are
FEATURE_WLAN_MCC_TO_SCC_SWITCH and FEATURE_LFR_SUBNET_DETECTION. The
make config process will add the CONFIG_ prefix to these Kconfig
entries.
