mds: prevent exceeding xattrs limits on initial set

When doing a sync setxattr (MDS_OP_SETXATTR) to set the first xattr in an
inode it is possible for the client to set a huge xattr key/value that would
exceed the limit.  Prevent this from from happening by checking the size
against the maximum allowed size.
