[GIT PULL] hfs/hfsplus changes for 7.2-rc1

[Viacheslav Dubeyko]

Hello Linus,

This pull request contains several fixes in HFS/HFS+ of syzbot
reported issues and HFS//HFS+ fixes of xfstests failures.

Edward Adam Davis has fixed a null-ptr-deref issue reported by
syzbot in hfsplus_create_attributes_file() for the case if
the attributes file is not loaded during system mount. Also,
it was added b-tree node size check in hfs_btree_open() with
the goal to prevent an uninit-value bug reported by syzbot
for the case of corrupted HFS+ image.

Rosen Penev suggested a nice fix in __hfs_bnode_create() by
using kzalloc_flex() instead of kzalloc().

Tristan Madani suggested really useful fix in hfs_bnode_read().
hfs_bnode_read() can return early without writing to the output buffer
when is_bnode_offset_valid() fails or when check_and_correct_requested_
length() corrects the length to zero.  Callers such as hfs_bnode_read_
u16() and hfs_bnode_read_u8() pass stack-allocated buffers and use the
result unconditionally, leading to KMSAN uninit-value reports.

The rest patches suggest teh fixes: (1) generic/637, generic/729 issue
for the case of HFS+ file system, (2) generic/003, generic/637
for the case of HFS file system.
