kernel: Remove numerous #include <sys/thread2.h>.

Most of them were added when we converted spl*() calls to
crit_enter()/crit_exit(), almost 14 years ago. We can now
remove a good chunk of them again for where crit_*() are
no longer used.

I had to adjust some files that were relying on thread2.h
or headers that it includes coming in via other headers
that it was removed from.

sys/dev/disk/dm: Fix device counter handling

dm_dev_list and its element counter dm_dev_counter should be
protected by the same lock dm_dev_mutex. Having these updated
separately makes code logic more complex than it should.

If dm_dev_counter is protected by dm_dev_mutex, then no need
to care if dm_dev_counter++/-- are atomic or not.

dm_pdev_alloc()/free()
* Fix memory leak.
* Rename dm_pdev_rem() to dm_pdev_free().
A simple kfree function should be xxx_free() but not xxx_rem().
xxx_rem() isn't necessarily a name used for just kfree() in
other files, which makes naming very confusing.
* Refactoring.

sys/dev/disk/dm: Separate dm_dev_rem_dev() from dm_dev_rem()

dm_dev_rem() should be separated into two functions where
one takes *dmv and the other takes name,uuid,minor for args.

If a caller has a pointer to dm device, then it basically
never use the rest. If not the caller may use all the rest.

dm_dev_rem() currently taking all four args makes it more
complicated than it should. Also this is closer to the
original NetBSD implementation.

dm - get rid of excessive locking and redundancy

* Just use dev->si_drv1 for the strategy, disk ioctl and dump as the
underlying device and 'dmv' is guaranteed not to go away. Keep the
locked approach (dm_dev_lookup) for open, close, and mapper ioctls to
ensure that we never rip out any node that's still in use.

* This eliminates exclusive locking in the IO path, which should
improve performance.
