fs/ntfs3: Fix attr_punch_hole() null pointer derenference

mainline inclusion
from mainline-v6.2-rc1
commit 6d5c9e79
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I683ER
CVE: CVE-2022-4842

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6d5c9e79b726cc473d40e9cb60976dbe8e669624



--------------------------------

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.
