[PATCH 3/7] staging: r8188eu: remove HW_VAR_AMPDU_MIN_SPACE from SetHwReg8188EU()

[Michael Straube <straube.linux@gmail.com>]

Remove the HW_VAR_AMPDU_MIN_SPACE case from SetHwReg8188EU() and move
its functionality to rtw_wlan_util.c where it is actually used. This
is part of the ongoing effort to get rid of the unwanted hal layer.
