disp: msm: use pm_runtime_resume_and_get instead of pm_runtime_get_sync

Browse Source 
pm_runtime_get_sync increases the usage_count refcount immaterial of
success/failure of the call, leading to invalid refcount on failures.
Use pm_runtime_resume_and_get instead, which takes care of reducing the
refcount on failure cases before returning from the function.
