Previously only a single thread could submit abort commands for admin
commands and it was the thread of the corresponding controller.
When we support multipath, we need to traverse the list of controllers
to which the target admin command is submitted. Threads of controllers
may be different.
On the other hand, the previous implementation made the I/O flow very
clean, but the I/O flow will not be clean if there are many controllers
and the subsystem does not have its thread.
This patch changes the policy so that any SPDK thread can submit abort
commands for admin commands.
Then when multipath is supported, we will be able to traverse the
list of controllers simply on the current thread to abort either I/O
command or admin command.
We already are able to submit any admin command on any thread anytime
including abort command. Hence this will not cause any issue.
