Subject: [PATCH v2] counter: ti-ecap-capture: Remove error print for
 devm_add_action_or_reset()

When `devm_add_action_or_reset()` fails, it is due to a failed memory
allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do
anything when error is `-ENOMEM`. Therefore, remove the useless call to
`dev_err_probe()` when `devm_add_action_or_reset()` fails, and just
return the value instead.
