block: add an API to atomically update queue limits
Add a new queue_limits_{start,commit}_update pair of functions that
allows taking an atomic snapshot of queue limits, update it, and
commit it if it passes validity checking. Also use the low-level
validation helper to implement blk_set_default_limits instead of
duplicating the initialization.
