We may someday support folios larger than 4GB, so use a size_t for the
byte count within a folio to prevent unpleasant truncations.

This function was overlooked when the write_begin and write_end address space
operations were removed as part of gfs2's iomap conversion.

With the traditional page-based writes, blocks are allocated separately
for each page written to. With iomap writes, we can allocate a lot more
blocks at once, with a fraction of the allocation overhead for each
page.
Split calculating the number of blocks that can be allocated at a given
position (gfs2_alloc_size) off from gfs2_iomap_alloc: that size
determines the number of blocks to allocate and reserve in the journal.
