Re: [syzbot] WARNING in iomap_iter

[Siddh Raman Pant]

Syzkaller posted a new reproducer unrelated to the issue causing
the older crash under this same issue, since the same function
triggers the newer warning.

This time it is related to erofs setting length equal to zero in
z_erofs_iomap_begin_report().

Thanks,
