dht: block/handle create op falling to decommissioned brick
Problem:
Post remove-brick start till commit phase, the client layout
may not be in sync with disk layout because of lack of lookup.
Hence,a create call may fall on the decommissioned brick.
Solution:
Will acquire a lock on hashed subvol. So that a fix-layout or
selfheal can not step on layout while reading the layout.
Even if we read a layout before remove-brick fix-layout and the
file falls on the decommissioned brick, the file should be
migrated to a new brick as per the fix-layout.
