ceph: Switch to generic xattr handlers
Add a catch-all xattr handler at the end of ceph_xattr_handlers. Check
for valid attribute names there, and remove those checks from
__ceph_{get,set,remove}xattr instead. No "system.*" xattrs need to be
handled by the catch-all handler anymore.
The set xattr handler is called with a NULL value to indicate that the
attribute should be removed; __ceph_setxattr already handles that case
correctly (ceph_set_acl could already calling __ceph_setxattr with a NULL
value).
Move the check for snapshots from ceph_{set,remove}xattr into
__ceph_{set,remove}xattr. With that, ceph_{get,set,remove}xattr can be
replaced with the generic iops.
