[PATCH] regulator: core: Fix argument to _notifier_call_chain call

[Axel Lin]

Pass the address of best_val rather than the value of best_val for the third
argument to _notifier_call_chain().

This fixes below build warning:
  CC      drivers/regulator/core.o
drivers/regulator/core.c: In function '_regulator_do_set_voltage':
drivers/regulator/core.c:2183:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
