drm: Fix memory leak at error path of drm_read()

Note that the read manpages explicitly states that the read position
is undefined on error. Since EFAULT is just a userspace bug we are
therefore fine with just dropping the event on the floor.

[danvet: Add note that just dropping the event is ok.]
