implementations, make nfs_symlink_filler() get the inode
from the page instead of passing it in from read_cache_page().

With all implementations of aops->readpage converted to aops->read_folio,
we can stop checking whether it's set and remove the member from aops.

This is a "weak" conversion which converts straight back to using pages.
A full conversion should be performed at some point, hopefully by

mpage_readpage still works in terms of pages, and has not been audited
for correctness with large folios, so include an assertion that the
filesystem is not passing it large folios. Convert all the filesystems
to call mpage_read_folio() instead of mpage_readpage().

This function is NOT converted to handle large folios, so include
an assert that the filesystem isn't passing one in. Otherwise, use
the folio functions instead of the page functions, where they exist.
Convert all filesystems which use block_read_full_page().

Change all the callers of ->readpage to call ->read_folio in preference,
if it exists. This is a transitional duplication, and will be removed
by the end of the series.

- Calculate iblock directly instead of using a while loop
- Move has_buffers to the end to remove a backwards jump
- Use __filemap_get_folio() instead of grab_cache_page(), which
removes a spurious FGP_ACCESSED flag.
- Eliminate length and pos variables
- Use folio APIs where they exist

We no longer need the page's inode pinned. This comment dates back to
commit db37648cd6 ("[PATCH] mm: non syncing lock_page()") which added
lock_page_nosync(). That was removed by commit 7eaceaccab ("block:
remove per-queue plugging") which also made this comment obsolete.
