staging: rtl8723bs: remove Hal_EfuseGetCurrentSize

The function Hal_EfuseGetCurrentSize is not used in the driver code,
remove it to get rid of dead code. As Hal_EfuseGetCurrentSize is the only
caller of hal_EfuseGetCurrentSize_WiFi and hal_EfuseGetCurrentSize_BT we
can remove these two functions as well.
