Zhang Qilong 535a1c43fd PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter
[ Upstream commit dd8088d5a8 ]

In many case, we need to check return value of pm_runtime_get_sync, but
it brings a trouble to the usage counter processing. Many callers forget
to decrease the usage counter when it failed, which could resulted in
reference leak. It has been discussed a lot[0][1]. So we add a function
to deal with the usage counter for better coding.
