[PATCH for-next 5/6] IB/hfi1: Use 4096 for default active MTU in query_qp

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

From: Jan Sokolowski <jan.sokolowski-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Currently, if a port is queried that has an invalid
Maximum Transmission Unit, driver reports default MTU of 2048.
This in incorrect.

Use default value of 4096 if invalid.
