mgmt/glusterd: handle error condition in quota fs crawl
mgmt/glusterd: handle error condition in quota fs crawl

Quota enable starts a crawl on the maintenance mount point, but if the chdir to
the mount point fails it will start the crawl on '/'. So the child should exit
with EXIT_FAILURE when the chdir fails.
