Subject: [PATCH] rapidio: remove reundant pointer md that is assigned but never read

From: Colin Ian King <colin.king@...onical.com>

Pointer md is assigned a value but it is never read, hence it is
redundant and can be removed. Cleans up clang warning:

drivers/rapidio/devices/rio_mport_cdev.c:1071:2: warning: Value stored
to 'md' is never read
