The 'did_zero' param of xfs_zero_range() was not passed to
iomap_zero_range() correctly. This was introduced by commit
7bb41db3ea16 ("xfs: handle 64-bit length in xfs_iozero"), and found
by code inspection.

Looks good.  Although this makes me wonder why we pass the
argument at all, given that it doesn't seem to matter :)

Joking aside: xfs_setattr_size seems to care to write out
the buffer cache zeroed byes, so this looks good to me:
