resize2fs: check for bogus new_size
If we don't check for new_size == 0, bogus values send resize2fs into
a tailspin:
resize2fs 1.41.0 (10-Jul-2008)
Illegal block number passed to ext2fs_test_block_bitmap #1 for block bitmap for
/tmp/tmp.lntZtMFvz8/fake-disk
...the same message repeated zillion times...
Probably should see where that loop is, but at any rate we should
error-check parse_num_blocks.
Thanks to Petr Muller for reporting this.
