[PATCH] xwayland: Activate and enable device on first capability reporting

[Boyan Ding]

Commit 2172714c changed behavior of capability handling, but it only
solved part of the problem. If Xwayland is launched without a capability
(e.g. no pointer device is connected when Xwayland was spinned up), and
later that capability comes, the device added will not be automatically
initialized. This patch initializes the device when the capability is
reported for the first time, thus avoiding the problem.
