Wang Hai e717f974ce samples/bpf: Fix the error return code of xdp_redirect's main() 
[ Upstream commit 7c6090ee2a ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

If bpf_map_update_elem() failed, main() should return a negative error.

Fixes: 832622e6bd ("xdp: sample program for new bpf_redirect helper")
