[Nbd] gznbd up to 2.9.23 incorrectly processes large "size" argument.

[Andrey <ahippo@...918...>]

Hi all,

gznbd works incorrectly with large size argument which overflows 4-byte integer.

For example:
gznbd /dev/nbd0 /root/test.gz 1000204886016
gznbd: 1000204886016 does not appear to be a valid size

The size is stored in u64, but is converted from string using atol().
I've attached the patch to replace atol() with atoll().
As the source is compiled with -std=gnu99, there must be no problem with atoll().
