[dpdk-dev] [PATCH] net/i40e: fix port close in FreeBSD

[Chenxu Di]

FreeBSD OS doesn't support igb_uio interrupt, so it will fail when
unregister the interrupt callback in port close. We can fix the issue by
passing -ENOENT when check the return value of unregister interrupt
callback function.

Fixes: ac89d46096d5 ("net/i40e: release port upon close")
