[PATCH 16/25] drm/msm/dpu: clean up test_only flag for RM reservation

[Jeykumar Sankaran <jsanka-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

Encoder uses test_only flag to differentiate RM reservations
invoked from atomic check and atomic_commit phases.
After reserving the HW blocks, if test_only was set, RM
releases the reservation. Retains them if not. Since we
got rid of RM reserve call from atomic_commit path, get rid
of this flag.
