media: sh_vou: fix pm_runtime_get_sync() usage count

[ Upstream commit 6e8b1526db164c9d4b9dacfb9bc48e365d7c4860 ]

The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.
Replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter, avoiding
a potential PM usage counter leak.

While here, check if the PM runtime error was caught at open time.
