Check for clientGone before sending events from XFixes (bug #1753).
Freeing resources during client closedown can cause cursor changes which
attempt to send cursor events through the XFixes extension; a client in the
process of closing down has no file to send events to, causing a crash when
this path is hit.
(cherry picked from commit 8a42af6a935b1cf0e15102e986bb527f4fab31a8)
