[GIT PULL] erofs fixes for 7.2-rc6

[Gao Xiang]

Hi Linus,

Could you consider these fixes for 7.2-rc6?

One patch fixes a new regression in page cache sharing introduced
in 7.2-rc3, which can cause a NULL pointer dereference; another
patch limits LZMA stream memory usage on systems with many CPUs.

Thanks,
Gao Xiang
