s3-sysquotas: remove special handling of EDQUOT
The sysquotas module has several supported backends for
getting/setting user/group quota. This patch removes a check
by the common code, to see if the backend has returned EDQUOT.
Before this patch, it was OK for a backend to return with error
and errno set to EDQUOT, and that meant success, but with a warning
that the user/group is over quota. This is the system behavior on
some Unices. This patch removes this from the protocol between the
sysquota module and its backend drivers - it's the responsibility
of the backend to return 0 iff it has fulfilled the request to get or
set quota.
