Tetsuo Handa 48960a503f fs: hfsplus: remove WARN_ON() from hfsplus_cat_{read,write}_inode() 
[ Upstream commit 81b21c0f01 ]

syzbot is hitting WARN_ON() in hfsplus_cat_{read,write}_inode(), for
crafted filesystem image can contain bogus length. There conditions are
not kernel bugs that can justify kernel to panic.
