drm/atomic: fix an error code in mode_fixup()

Browse Source 
commit f9ad86e42d0303eeb8e0d41bb208153022ebd9d2 upstream.

Having "ret" be a bool type works for everything except
ret = funcs->atomic_check().  The other functions all return zero on
error but ->atomic_check() returns negative error codes.  We want to
propagate the error code but instead we return 1.

I found this bug with static analysis and I don't know if it affects
run time.
