[PATCH 1/2] drm/v3d: Fix PM reference leak in v3d_get_param_ioctl()

[Yu Kuai]

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
