[PATCH] IB/srp: introduce print_hex_dump()

[Bart Van Assche]

Reduces the number of source code lines in ib_srp.c by replacing an explicit
loop by a call to print_hex_dump().

I like the idea, minor nit in that we loose the SCSI prefix that tells
use which host device printed it. Then again it's a debugging aid, so I
don't know that it matters all that much.

Easily solvable with s/""/dev_name(target->scsi_host.shost_gendev)/

Hmm, that may be more ugly than it is worth.
