[GIT PULL] hfs/hfsplus changes for 6.17-rc1

[Viacheslav Dubeyko <slava@dubeyko.com>]

Hello Linus,

Currently, we have around 221 opened issues in HFS/HFS+ file system
drivers. Mostly, xfstests reveal majority of the issues and multiple
tests leave HFS/HFS+ volume in corrupted state.

Johannes Thumshirn has made nice cleanup in hfsplus_submit_bio().
Tetsuo Handa has fixed the syzbot reported issue in
hfsplus_create_attributes_file() for the case of corruption
the Attributes File's metadata. Yangtao Li has fixed the syzbot
reported issue by removing the uneccessary WARN_ON() in
hfsplus_free_extents().

The rest patches contains fixes:
(1) restoring generic/001 successful execution by erasing
deleted b-tree nodes;
(2) eliminating slab-out-of-bounds issue in hfs_bnode_read()
and hfsplus_bnode_read() by checking correctness of offset and
length by operation of accessing b-tree node's content;
(3) eliminating slab-out-of-bounds read in hfsplus_uni2asc()
for the case if b-tree node's record has corrupted length of
a name that could be bigger than HFSPLUS_MAX_STRLEN;
(4) eliminating general protection fault in hfs_find_init()
for the case of initial b-tree object creation.
