A change of return status was introduced in commit 3fffd1283927
("i2c: allow specifying separate wakeup interrupt in device tree")

The commit prevents the defer status being passed up the call stack
appropriately when dev_pm_domain_attach returns -EPROBE_DEFER.

Catch the PROBE_DEFER and clear up the IRQ wakeup status

Fixes: 3fffd1283927 ("i2c: allow specifying separate wakeup
interrupt in device tree")

V2:
 Fall through the error path before returning -EPROBE_DEFER

V3:
 Drop the if/else for cleaner code path
