[PATCH] Input: gpio-keys - use devm_add_action_or_reset

[Sudip Mukherjee]

If devm_add_action() fails we are printing the error message and
returning but we have already setup a delayed work or a timer.
Lets now use the helper devm_add_action_or_reset() and return and in
case of error the cleanup function will be called by the helper to
cancel the delayed work or to delete the timer.
