Subject: [PATCH iproute2-next 04/11] m_vlan: fix formatting of push ethernet src mac

This was reported as a clang warning:
    CC       m_vlan.o
m_vlan.c:282:32: warning: converting the enum constant to a boolean [-Wint-in-bool-context]
                if (tb[TCA_VLAN_PUSH_ETH_SRC &&
                                             ^

But it is really a bug in the code for displaying the pushed
source mac.
