Got SIGSEGV fault while running kms_dp_dsc test but did not
connect DP DSC capable monitor on eDP/DP port. This test daemon
should "SKIP" test without any problem. We found kms_dp_dsc
can't get proper drmModeConnector and caused this SIGSEGV fault
when release it. Make sure drmModeConnector is available before
free it can avoid this issue.
