pwm: omap-dmtimer: Simplify error handling

[ Upstream commit c4cf7aa57eb83b108d2d9c6c37c143388fee2a4d ]

Instead of doing error handling in the middle of ->probe(), move error
handling and freeing the reference to timer to the end.

This fixes a resource leak as dm_timer wasn't freed when allocating
*omap failed.

Implementation note: The put: label was never reached without a goto and
ret being unequal to 0, so the removed return statement is fine.

Fixes: 6604c6556db9 ("pwm: Add PWM driver for OMAP using dual-mode timers")
