[PATCH] v9fs: readlink extended mode check

LANL reported some issues with random crashes during mount of legacy protocol
servers (9P2000 versus 9P2000.u) -- crash was always happening in readlink
(which should never happen in legacy mode).  Added some sanity conditionals to
the get_inode code which should prevent the errors LANL was seeing.  Code
tested benign through regression.
