[PATCH libnftables] expr: fix incorrect data type for several expression object fields

[Pablo Neira Ayuso <pablo@netfilter.org>]

This patch fixes the incorrect data type (from uint8_t to uint32_t) in
several private data area of the expressions.

It cleans up this by translating several unsigned int to uint32_t.
