[GIT PULL] erofs more updates for 7.3-rc1

[Gao Xiang]

Hi Linus,

Could you consider these extra patches for 7.3-rc1?

All commits are quite small, so I guess there's no need to delay them.

One patch from Geert addresses EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS
again, so that "make savedefconfig" won't write the needless default
value to the defconfig file. It avoids unnecessarily enlarging the
defconfig files and reduces churn when updating them.

In addition, there are small changes to enhance the page cache sharing
feature to support SEEK_{HOLE,DATA}, splice(), and large folios.

The remaining one fixes an issue in z_erofs_gbuf_growsize() as below.

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

Thanks,
Gao Xiang
