vmwgfx: remove identical branches

[Dave Jones <davej@redhat.com>]

Commit 8b7de6aa8468: "vmwgfx: Rework fence event action" removed the
tv_sec & tv_usec arguments to vmw_event_fence_action_create, which meant
that both sides of the if/else are now exactly the same.

Remove the flag check, and just do it unconditionally.

Spotted with Coverity.
