[Intel-gfx] [PATCH i-g-t] kms_atomic_transition: Remove skip_on_unsupported_nonblocking_modeset.

[Maarten Lankhorst]

This weas a workaround to gracefully skip on i915 before nonblocking
modeset support was added, but this is no longer needed. Remove the
code, since it's safe to always assume such support is enabled.
