nvme: split nvme_kill_queues

Browse source 
nvme_kill_queues does two things:

 1) mark the gendisk of all namespaces dead
 2) unquiesce all I/O queues

These used to be be intertwined due to block layer issues, but aren't
any more.  So move the unquiscing of the I/O queues into the callers,
and rename the rest of the function to the now more descriptive
nvme_mark_namespaces_dead.
