Subject: [PATCH v1 1/1] fs/ntfs3: Fix compilation error

Compilation with CONFIG_WERROR=y, which is default, is broken:

  fs/ntfs3/super.c:1247:26: error: variable 'attr' is uninitialized when used here [-Werror,-Wuninitialized]

  attr = ni_find_attr(ni, attr, NULL, ATTR_VOL_INFO, NULL, 0, NULL, NULL);
				^~~~
Pass NULL instead.

Fixes: 82cae269cfa9 ("fs/ntfs3: Add initialization of super block")
