[PATCH 2/2] brd: remove redundent prefix with pr_fmt macro

[Chaitanya Kulkarni <kch@nvidia.com>]

Define pr_fmt to "brd: " in order to remove the duplicate brd prefix
that makes pr_xxx() longer than it's needed. Note that this practice
is been followed in most of the kernel module for the consistency of
the driver messages so they become easy to grep/debug and not duplicate
driver name in the pr_xxx() messages,
