If remove the space used by both group and project quota all failed, the first
error will be hidden.
Actually, I'm confused to compare the code logical between the kernel and the
user space even without this feature. i.e. xfsprogs/quota/state.c->remove_extents():

if (type & XFS_USER_QUOTA) {
if (remove_qtype_extents(dir, XFS_USER_QUOTA) < 0)
return;
^^^^^^^^ <-- So we will return and won't continue to deal with
other quota types. However, in kernel part, we deal with those types all at once.
}
if (type & XFS_GROUP_QUOTA) {
if (remove_qtype_extents(dir, XFS_GROUP_QUOTA) < 0)
return;
} else if (type & XFS_PROJ_QUOTA) {
if (remove_qtype_extents(dir, XFS_PROJ_QUOTA) < 0)
return;
}
