[PATCH] ntb: ntb_pingpong: remove redundant initialization of variables msg_data and spad_data

[Colin King]

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

The variables msg_data and spad_data are being initialized with values
that are never read, they are being updated later on. The initializations
are redundant and can be removed.
