Matthew Wilcox (Oracle) d454ab82bc iomap: Allow iomap_write_begin() to be called with the full length
In the future, we want write_begin to know the entire length of the
write so that it can choose to allocate large folios.  Pass the full
length in from __iomap_zero_iter() and limit it where necessary.
