[PATCH 01/21] staging/rdma/hfi1: Add spaces around binary operators

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

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

Add spaces around binary operators.

Fixes checkpatch check:
CHECK: spaces preferred around that 'x'
where x is a binary operator
