Subject: [PATCH] [SCSI] bnx2i: add a prefix to a printk

During each suspend and resume cycle a mysterious message is added to
the logs:
    CPU 1 offline: Remove Rx thread

Some grepping of the tree revealed this message is printed by bnx2i.
Add a prefix to this message to make it clear that it is printed by
bnx2i. That should also make it obvious it is the mirror of the
    bnx2i: CPU 1 online: Create Rx thread

message.

0) Untested!

1) I only noticed this because I've been looking at the log messages
generated by suspend and resume (for some iwlegacy and i915 issues) and
because Fedora 16 enables bnx2i by default.

2) This triggers a checkpatch warning:
    WARNING: Prefer pr_info(... to printk(KERN_INFO, ...

So I added Joe to the Cc's to suggest a way to make all printks in this
file end up with a "bnx2i:" prefix (or whatever prefix is preferred).
