Documentation: PM: Clarify pm_runtime_resume_and_get() return value
[ Upstream commit ccb84dc8f4a02e7d30ffd388522996546b4d00e1 ]
Update the documentation to match the behaviour of the code.
pm_runtime_resume_and_get() always returns 0 on success, even if
__pm_runtime_resume() returns 1.
Fixes: 2c412337cfe6 ("PM: runtime: Add documentation for pm_runtime_resume_and_get()")
