[ext2resize] possible overflow bug in ext2_block_iterate()

[Coywolf Qi H. <co...@gm...>]

Hello,

In ext2.c::ext2_block_iterate(), there is "int count"; but i_blocks is
u32. count overflows when (i_blocks >=3D 1 << 31). I'd fix count to u64.
Comments?

Ignore it. No problem, no overflow for now, since we don't handle
triple-indirect blocks.
