[PATCH] statfs: remove redundant pointer sb

[PATCH] statfs: remove redundant pointer sb

[Colin King]

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

Pointer sb is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'sb' set but not used [-Wunused-but-set-variable]
