[PATCH][next] staging: rtl8723bs: remove redundant variable hoffset

[Colin Ian King]

Variable hoffset in functions hal_EfuseGetCurrentSize_WiFi and
hal_EfuseGetCurrentSize_BT is being assigned a value but it not
being read for any useful reason at all. The variable is redundant
and can be removed.

Cleans up clang scan build warnings for lines 957 and 1050:
drivers/staging/rtl8723bs/hal/rtl8723b_hal_init.c:957:5: warning:
variable 'hoffset' set but not used [-Wunused-but-set-variable]
