cifs: Handle transition to filemap_get_folios_tag()
filemap_get_folios_tag() is being added and find_get_pages_range_tag() is
being removed in effectively a single event. This causes a problem for
the:
cifs: Change the I/O paths to use an iterator rather than a page list
patch[1] on the cifs/for-next branch as it's adding a new user of the
latter (which is going away), but can't yet be converted to using the
former (which doesn't yet exist upstream).
Here's a conversion patch that could be applied at merge time to deal with
this. The new cifs_writepages_region() is based directly on
afs_writepages_region() and the AFS changes in the mm tree[2]:

afs: convert afs_writepages_region() to use filemap_get_folios_tag()
can be replicated in cifs almost exactly.
