vgsp-disp: retry a lost UPDATE completion event from the pump

r1636: the X-start mode set wrote FINISHED but the channel completion
event was refused (event burst cap / transient status-queue state) and
never retried, so NVKMS waited forever and X wedged in
os_acquire_rwlock_write.  Mark the channel event_pending on a failed
post, retry it every pump pass (outside disp.lock), clear on success,
and log the failure/recovery plus hObj in the UPDATE line.
