[GIT PULL] erofs fixes for 6.1-rc6

[Gao Xiang]

Hi Linus,

Could you consider these three fixes for 6.1-rc6?

Most patches randomly fix error paths or corner cases in fscache mode
reported recently.  And the rest one fixes an invalid access relating
to fragments on crafted images.  Details are shown as below.

I should submit earlier for -rc5 but actually delay a bit since one
commit message got minor updated.  All commits have been in linux-next
and no merge conflicts.

Thanks,
Gao Xiang
