drm/vc4: vec: Use pm_runtime_resume_and_get() in vc4_vec_encoder_enable()

Browse source

Commit f0601ef863 ("drm/vc4: vec: Protect device resources after
removal") add fail path for vc4_vec_encoder_enable(), and will put
usage_counter only when pm_runtime_get_sync() succeeds. However,
pm_runtime_get_sync() will increment usage_counter even it failed. Fix
it by replacing it with pm_runtime_resume_and_get() to keep usage
counter balanced.
