recently revealed breakages that had it causing issues even for cases
where it isn't required made me re-pull the trigger on this one. It's
known broken and nobody has stepped up to maintain the code

multishot where appropriate

currently under exclusively ownership/open

block: prevent adding/deleting disk during updating nr_hw_queues

Both adding/deleting disk code are reader of `nr_hw_queues`, so we can't
allow them in-progress when updating nr_hw_queues, kernel panic and
kasan has been reported in [1].

Prevent adding/deleting disk during updating nr_hw_queues by adding
rw_semaphore to tagset, write lock is grabbed in blk_mq_update_nr_hw_queues(),
and read lock is acquired when adding/deleting disk.

Also mark GFP_NOIO allocation scope for adding/deleting disk because
blk_mq_update_nr_hw_queues() is part of some driver's error handler.

This way avoids lot of trouble.
