[PATCH] scsi: libsas: remove redundant assignment to variable res

[PATCH] scsi: libsas: remove redundant assignment to variable res

[Colin King]

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

The variable res 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.
