From: Yunjian Wang <wangyunj...@huawei.com>
The ethdev port id should be 16 bits now. This patch fixes the data
type of the variable for 'pid', changing from uint32_t to uint16_t.
We also need use RTE_BUILD_BUG_ON() to ensure that RTE_MAX_ETHPORTS
is less or equal to UINT16_MAX.
Fixes: 5b7ba31148a8 ("ethdev: add port ownership")
