[PATCH 15/17] IB/hfi1: Handle host handshake timeout

[Dennis Dalessandro <dennis.dalessandro-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

From: Jubin John <jubin.john-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Host handshake timeout can occur during the verify capability
state. This is a LNI related failure and should be
handled in the same way as other LNI failures.
