dpif-netdev: Fix a compilation warning

Browse Source 
Building OVS tree without DPDK produced the following warning message:
    lib/dpif-netdev.c:1868:5: error: statement with no effect

This error message is complaining the return value of the following
macro not being used.
	#define pmd_thread_setaffinity_cpu(c) (0)

The patch fixed this warnning by making the stub functions
as inline funtions.
