Christoph Hellwig 54e7d59841 nfs: drop the incorrect assertion in nfs_swap_rw()
Since commit 2282679fb2 ("mm: submit multipage write for SWP_FS_OPS
swap-space"), we can plug multiple pages then unplug them all together. 
That means iov_iter_count(iter) could be way bigger than PAGE_SIZE, it
actually equals the size of iov_iter_npages(iter, INT_MAX).

Note this issue has nothing to do with large folios as we don't support
THP_SWPOUT to non-block devices.

[v-songbaohua@oppo.com: figure out the cause and correct the commit message]
