LU-12678 lnet: discard LNET_MD_PHYS

This macro has no value and is never set.
It claims "compatibility with Cray Portals", yet cray-dvs
   git://github.com/glennklockwood/cray-dvs.git
does not use it in any non-trivial way.

Much has changed in lnet and lib-md since 2007 when this
value was added - it seems likely that this really
is dead.

So remove it.  If/when this results in problems, it can
easily be re-added and more details can be provided at
that time.
