[PATCH 15/15] thermal/drivers/samsung: acpm-tmu: Simplify pm_runtime_resume_and_get() error checks

[Tudor Ambarus]

Unlike pm_runtime_get_sync(), pm_runtime_resume_and_get() returns 0 on
success or a negative error code on failure. Check "if (ret)"
consistently across all pm_runtime_resume_and_get() call sites in
acpm-tmu.c.
