staging: rtl8723bs: clean up variable initializations

After previous cleanup patches the variable initializations in
hal_EfuseSwitchToBank are messed up a little, but were left as-is to make
reviewing easier. For example bRet is initialized to false and immediately
set to true. This patch cleans up the variable initializations.
