drm/v3d: Skip perfmon serialization while a global perfmon is set
A global perfmon counts concurrent activity from every job, so no
dependency is added while one is set. Skip the accumulator for the jobs
carrying no perfmon while a global perfmon is enabled, which is every job
in the common case.
Jobs carrying their own perfmon stay tracked. The global perfmon may be
cleared before such a job runs, and the next job carrying a perfmon has
to wait for it, otherwise both are in flight at once and only one gets
programmed in the HW.
