Revert "block: freeze the queue earlier in del_gendisk"
This reverts commit a09b314005f3a0956ebf56e01b3b80339df577cc.
Dusty Mabe reported consistent hang during CoreOS shutdown with a MD
RAID1 setup. Although apparently similar hangs happened before,
and this patch most likely is not the root cause it made it much
more severe. Revert it until we can figure out what is going on
with the md driver.
