fuse: remove page alignment check for writeback len
Remove incorrect page alignment check for the writeback len arg in
fuse_iomap_writeback_range(). len will always be block-aligned as
passed in by iomap.
On regular fuse filesystems, i_blkbits is set to PAGE_SHIFT so this is
not a problem but for fuseblk filesystems, the block size is set to a
default of 512 bytes or a block size passed in at mount time.
Please note that non-page-aligned lengths are fine for the logic in
fuse_iomap_writeback_range(). The check was originally added as a
safeguard to detect conspicuously wrong ranges.
