qcacld-3.0: Handle epping disable and epping close during rmmod

In hdd_soc_remove, epping_disable/epping_close are called after
hif context is cleared by hdd_wlan_stop_modules.
hif context is needed to cleanup epping adapter and since hif
context is not available during epping disable/close, epping
adapter cleanup fails.

Handle epping_disable & epping_close by moving them to
hdd_wlan_stop_modules before hif is closed
