Subject: [PATCH] net/hns3: fix variable overflow

[ upstream commit 52d4c3c4872be23c173ea14d5d7a5f71ef217bdc ]

The number of interrupt vector may exceed the range of uint8_t.
So hns3_unmap_rx_interrupt() should use uint16_t for 'vec' variable.

Fixes: 02a7b55657b2 ("net/hns3: support Rx interrupt")
