libext2fs: Use blk_t instead of int in ext2fs_allocate_group_table

We are using a signed int to store a block number in
ext2fs_allocate_group_table.  We don't actually do any computation or
comparisons using it, so it shouldn't cause any bugs, but it's
technically incorrect, and it's possible an overly clever compiler
might do something wrong with it.
