Don't allow VOP_GETEXTATTR to set uio->uio_offset != 0, as we don't
provide locking over extended attribute operations, requiring that
individual operations be atomic. Allowing non-zero starting offsets
permits applications/etc to put themselves at risk for inconsistent
behavior. As VOP_SETEXTATTR already prohibited non-zero write offsets,
this makes sense.
