[GIT PULL] erofs fixes for 5.5-rc2

[Gao Xiang]

Hi Linus,

Could you consider these fixes for this 5.5 round?

Mainly address a regression reported by David recently observed
together with overlayfs due to the improper return value of listxattr()
without xattr. Update outdated expressions in document as well.

Thanks,
Gao Xiang
