[PATCH] fs/ntfs3: Remove unused al_delete_le

[linux]

From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

'al_delete_le' was added by:
Commit be71b5cba2e6 ("fs/ntfs3: Add attrib operations")

but has remained unused; there is an al_remove_le which seems
to be being used instead.

Remove 'al_delete_le'.
