In case IFS was modified in the environment where print_backtrace()
was called, it could impact the cmd substitution used for seq'ing
the main FUNCNAME loop. Example:
========== Backtrace start: ==========
/home/vagrant/spdk_repo/spdk/test/common/autotest_common.sh: line 980: 1
2
3
4: syntax error in expression (error token is "2

Avoid that by resetting the IFS to its default value, but also,
replace said $() with arithmetic evaluation to avoid it altogether.

This UT was not working as intended, and was covered by

A single _reactor_run() iterates over all active pollers.
If at least one returns busy, so does the thread.
Thread load at the begining of UT is not 'low', but 100% busy.
To emulate loads outside of the 100% busy/idle, multiple
spdk_thread_polls need to be exectued.
As such to keep this case simple, the busy poller is removed.

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.

Initialize ANA state of each namespace to optimized regardless of
whether ANA is supported or not. This will simplify the code to get
the optimal I/O path because we do not have to care if the namespace
supports ANA.

It is unlikely that managing namespaces by nvme_bdev is complicated.
Hence we do not need the helper function nvme_bdev_to_bdev_ns().

We can hold bdev_io directly in nvme_bdev_ctrlr as an outstanding reset.
We can put spdk_bdev_io_from_ctx(bio) into a parameter for a few
functions because it is used only once in a function.
Passing not spdk_bdev_io but nvme_bdev_io to bdev_nvme_verify_pi_error()
remove unnecessary substitution.
This is a little more efficient and simplifies the implementation.
