power: supply: twl4030_charger: correct comparision with old current
Driver reads existing current value from two 8-bit registers, but then
compares only one of them with the new 16-bit value. clang W=1 is also
not happy:
twl4030_charger.c:243:16: error: variable 'cur_reg' set but not used [-Werror,-Wunused-but-set-variable]
