[PATCH 1/2] staging: rtl8723bs: remove unused AMPDU burst mode

[Adriano Cordova]

AMPDUBurstMode is never written anywhere in the driver. HalData is
vzalloc'd, so the field is always 0, and the sole read in
_InitBurstPktLen_8723BS() is therefore always false. The only use of
REG_AMPDU_BURST_MODE_8723B is the guarded rtw_write8() that this
branch protects, so that register write never executes. Remove the
field, its enum and the dead branch.
