media: camss: Fix a reference count leak.

[ Upstream commit d0675b67b42eb4f1a840d1513b5b00f78312f833 ]

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code, causing incorrect ref count if
PM runtime put is not called in error handling paths.
Thus call pm_runtime_put_sync() if pm_runtime_get_sync() fails.

Fixes: 02afa816dbbf ("media: camss: Add basic runtime PM support")
