[PATCH] sata_nv: remove redundant pointers sdev0 and sdev1

[PATCH] sata_nv: remove redundant pointers sdev0 and sdev1

[Colin King]

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

Pointers sdev0 and sdev1 are being assigned but are never used hence they
are redundant and can be removed.

Cleans up clang warnings:
warning: variable 'sdev0' set but not used [-Wunused-but-set-variable]
warning: variable 'sdev1' set but not used [-Wunused-but-set-variable]
