[PATCH 1/2] batctl: event: Fix direct parsing on hardif for set_hardif

[Sven Eckelmann]

The code to get the hard interface name for an even was accidentally
checking for BATADV_ATTR_MESH_IFNAME instead of BATADV_ATTR_HARD_IFNAME. As
result, the fallback code was always used when BATADV_ATTR_MESH_IFNAME
would have not been available.

Luckily, at the moment, BATADV_ATTR_HARD_IFNAME is always available when
BATADV_ATTR_MESH_IFNAME is set BATADV_CMD_SET_HARDIF events.

Fixes: d12322eeb361 ("batctl: event: Get ifname from netlink message")
