Subject: [PATCH 2/2] i2c: omap: Fix an error handling path in omap_i2c_probe()

If an error occurs after pm_runtime_use_autosuspend(), a corresponding
pm_runtime_dont_use_autosuspend() should be called.

In case of error in pm_runtime_resume_and_get(), it is not the case because
the error handling path is wrongly ordered.
Fix it.

Fixes: 780f62974125 ("i2c: omap: fix reference leak when pm_runtime_get_sync fails")
