b48781aa6c fixed multiple bugs where the
display wasn't flushed correctly, however it was a little overzealous.
Some of the flushes were added after calls that only updated internal
state, some in internal functions in which the caller was already going
to flush, and some were after wayland protocol calls that are double
buffered anyway and won't do anything until a following commit.
Also, I've removes at least one long standing flush where the recently
added flush is in a better location than the original.
in the case where a connection was not actively rendering, there was nothing
which would trigger a display flush, leading to applications potentially
deadlocking

Summary:
printf %m stringifies and prints errno. I've tried to remove its use
anywhere that the immediately preceding function might not set errno
or is a complicated function for which knowing errno doesn't really
give any useful information.
I've left a few of the drmMode calls because they're just wrappers
around ioctl, which legitimately sets errno.
