[PATCH] regulator: core: Fix unused variable warning

[Sascha Hauer]

When CONFIG_DEBUG_LOCK_ALLOC is not enabled, we get:
  drivers/regulator/core.c: In function 'regulator_lock_supply':
  drivers/regulator/core.c:142:6: warning: unused variable 'i' [-Wunused-variable]

Fix this by adding a __maybe_unused annotation.
