regulator: core: Fix short description for _regulator_check_status_enabled()

kernel-doc complains that _regulator_check_status_enabled() is missing a
short description.

Since the current description is already quite short, just trim it a bit
more and use it as the short description.

Fixes: f7d7ad42 ("regulator: Allow regulators to verify enabled during enable()")
