IB/ipath: Prevent link-recovery code from negating admin disable
The link can be put in LINKDOWN_DISABLE state either locally or via a
MAD. However, the link-recovery code will take it out of that state as
a side-effect of attempts to clear SerDes/XGXS issues.
We add a flag to indicate "link is down on purpose, leave it alone."
