ublk: don't issue uring_cmd from fallback task work
When ublk_ch_uring_cmd_cb() runs as fallback task work (e.g., because
the submitting task is exiting), the command should not be issued as
current is a kworker, not the daemon task. This can cause io->task
to capture the wrong task in __ublk_fetch(), leading to a task
mismatch warning in ublk_uring_cmd_cancel_fn().
Check tw.cancel and return -ECANCELED instead of issuing the command
from fallback context.
