io_uring: fix not released cached task refs
commit 3cc7fdb9f90a25ae92250bf9e6cf3b9556b230e9 upstream.
tctx_task_work() may get run after io_uring cancellation and so there
will be no one to put cached in tctx task refs that may have been added
back by tw handlers using inline completion infra, Call
io_uring_drop_tctx_refs() at the end of the main tw handler to release
them.
