media: stm32-dcmi: fix check of pm_runtime_get_sync return value



commit ab41b99e upstream.

Start streaming was sometimes failing because of pm_runtime_get_sync()
non-0 return value. In fact return value was not an error but a
positive value (1), indicating that PM was already enabled.
Fix this by going to error path only with negative return value.
