iomap: avoid avoid truncating 64-bit offset to 32 bits
[ Upstream commit c13094b894de289514d84b8db56d1f2931a0bade ]
on 32-bit kernels, iomap_write_delalloc_scan() was inadvertently using a
32-bit position due to folio_next_index() returning an unsigned long.
This could lead to an infinite loop when writing to an xfs filesystem.
