[08/10] fs: convert simple use of generic_file_*_mmap() to .mmap_prepare()

Commit Message

Lorenzo Stoakes June 16, 2025, 7:33 p.m. UTC 
Since commit c84bf6dd2b83 ("mm: introduce new .mmap_prepare() file
callback"), the f_op->mmap() hook has been deprecated in favour of
f_op->mmap_prepare().

We have provided generic .mmap_prepare() equivalents, so update all file
systems that specify these directly in their file_operations structures.

This updates 9p, adfs, affs, bfs, fat, hfs, hfsplus, hostfs, hpfs, jffs2,
jfs, minix, omfs, ramfs and ufs file systems directly.

It updates generic_ro_fops which impacts qnx4, cramfs, befs, squashfs,
frebxfs, qnx6, efs, romfs, erofs and isofs file systems.

There are remaining file systems which use generic hooks in a less direct
way which we address in a subsequent commit.
