layout: Drop fallback for hot corner without barriers
The BARRIER backend capability was been moot for a long time since
XInput 2.4 became widespread and barriers became commonplace. And
even further recently with the removal of the X11 backend. The
native backend has always implemented barriers.
It seems we can drop this fallback handling. Since the _entered flag
was only used in those paths, the leave event vfunc is unnecessary too.
