Rouven Czerwinski cdd9a60f72 Revert "backend/drm: Check if output is enabled before sending frame event" 
This reverts commit 85757665e6.

We now check if the output is enabled within wlr_output_send_frame, no
need to handle this explicitly in the DRM backend. This also fixes a
race which was introduced with this commit: if we schedule the flip,
disable and commit the output before the flip happens,
output.frame_pending will not be reset to false. We than always fail to
enable the output subsequently:

since the basic_output_test will always fail.
Reset frame_pending to false even if the output has been disabled in the
meantime.
