[PATCH v2 2/8] staging: r8188eu: remove HW_VAR_MLME_DISCONNECT from SetHwReg8188EU()

SetHwReg8188EU() is called with HW_VAR_MLME_DISCONNECT only from
functions in rtw_mlme_ext.c. Move the functionality into a static
function in rtw_mlme_ext.c and remove the HW_VAR_MLME_DISCONNECT case
from SetHwReg8188EU(). This is part of the ongoing effort to get rid
of the unwanted hal layer.
