Subject[PATCH] ocfs2: remove some redundant assignments
Date
From: Colin Ian King <colin.king@canonical.com>

The initialization of free_space is redundant as free_space is
updated later on and the initialized value is hence never used.

The pointer new_list is set but never used so it can be completely
removed.

Cleans up clang scan-build warnings.
"Value stored to 'free_space' during its initialization is never read"
"Value stored to 'new_list' is never read"
