[PATCH -next] power: supply: charger-manager: Remove unused but set variable 'charger'

Gcc report warning as follows:

drivers/power/supply/charger-manager.c:1626:29: warning:
 variable 'charger' set but not used [-Wunused-but-set-variable]
 1626 |   struct charger_regulator *charger;
      |                             ^~~~~~~

After c1f73028f75d ("power: supply: charger-manager: Update extcon
functions"), 'charger' is never be used, so removing it to avoid
build warning.
