libhwc2.1: resolving histogram_request_ioctl error log
When screen in idle, DRM driver would not respond
and the DRM request would not be satisfied.
Later on, when another histogram client calls,
DRM driver will complain histogram already registered error log.
Skip the request call if the previous one is there.
Bug: 236907095
Test: local test and verified without error log
