tools/ocaml/libs/xb: Do not crash after xenbus is unmapped

Xenmmap.unmap sets the address to MAP_FAILED in xenmmap_stubs.c.  If due to a
bug there were still references to the Xenbus and we attempt to use it then we
crash.  Raise an exception instead of crashing.

(cherry picked from commit 5e317896342d553f0b55f72948bbf93a0f1147d3)
