[PATCH] bond: changed port_id type to uint8_t to prevent data loss.

[PATCH] bond: changed port_id type to uint8_t to prevent data loss.

[Maciej Gajdzica]

In some places port_id is declared as int, which causes data loss when
using functions expecting port_id as uint8_t. Issue found with static
code analysis tool.
