transaction: Mark client resize immediately ready

If a client commits a new size on its own, we create a transaction for
the resize like any other. However, this involves sending a configure
and waiting for the ack, and wlroots will not send configure events when
there has been no change. This leads to transactions timing out.

Instead, just mark the view ready immediately by size when the client
is already ready, so that we avoid waiting for an ack that will never
come.
