cluster/dht: Fix min-free-disk calculations when quota-deem-statfs is on
PROBLEM: As part of file creation, DHT sends a statfs call to all of its sub-volumes and expects in return the local space consumption and availability on each one of them. This information is used by DHT to ensure that atleast min-free-disk amount of space is left on each sub-volume in the event that there ARE other sub-volumes with more space available. But when quota-deem-statfs is enabled, quota xlator on every brick unwinds the statfs call with volume-wide consumption of disk space. This leads to miscalculation in min-free-disk algo, thereby misleading DHT at some point, into thinking all sub-volumes have equal available space, in which case DHT keeps sending new file creates to subvol-0, causing it to become 100% full at some point although there ARE other subvols with ample space available. FIX: The fix is to make quota_statfs() behave as if quota xlator weren't enabled, thereby making every brick return only its local consumption and disk space availability.
