gpio: of: Fix handling for deferred probe for -gpio suffix
Commit dd34c37aa3e (gpio: of: Allow -gpio suffix for property names) added parsing for both -gpio and -gpios suffix but also changed the handling for deferred probe unintentionally. Because of the looping the second name will now return -ENOENT instead of -EPROBE_DEFER. Fix the issue by breaking out of the loop if -EPROBE_DEFER is encountered.
