rwatson 51a3d7f35d 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.
