9p/trans_fd: put worker reqs on destroy
[ Upstream commit fb488fc1f2b4c5128540b032892ddec91edaf8d9 ]
p9_read_work/p9_write_work might still hold references to a req after
having been cancelled; make sure we put any of these to avoid potential
request leak on disconnect.
Fixes: 728356dedeff8 ("9p: Add refcount to p9_req_t")
