fs/ntfs3: Fix attr_punch_hole() null pointer derenference
commit 6d5c9e79b726cc473d40e9cb60976dbe8e669624 upstream.
The bug occours due to a misuse of `attr` variable instead of `attr_b`.
`attr` is being initialized as NULL, then being derenfernced
as `attr->res.data_size`.
This bug causes a crash of the ntfs3 driver itself,
If compiled directly to the kernel, it crashes the whole system.
