erofs fixes for 6.10-rc7

Hi Linus,

Could you consider these patches for 6.10-rc7?

The most important one fixes possible infinite loops reported by a smartphone vendor OPPO recently due to some unexpected zero-sized compressed pcluster out of interrupted I/Os, storage failures, etc.

Another patch fixes global buffer memory leak on unloading, and the remaining one switches to use super_set_uuid() to keep with the other filesystems.

All commits have been in -next for a while and no potential merge conflict is observed.

Thanks,
Gao Xiang
