[PATCH] IB/hfi1: remove redundant assignment to variable ret

[PATCH] IB/hfi1: remove redundant assignment to variable ret

[Colin King]

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

The variable ret is being initialized with a value that is never
read and it is being updated later with a new value. The
initialization is redundant and can be removed.
