ceph: return -ERANGE if virtual xattr value didn't fit in buffer
[ Upstream commit 3b421018f48c482bdc9650f894aa1747cf90e51d ]
The getxattr manpage states that we should return ERANGE if the
destination buffer size is too small to hold the value.
ceph_vxattrcb_layout does this internally, but we should be doing
this for all vxattrs.
Fix the only caller of getxattr_cb to check the returned size
against the buffer length and return -ERANGE if it doesn't fit.
Drop the same check in ceph_vxattrcb_layout and just rely on the
caller to handle it.
