[ Upstream commit b4201cc4fc6e1c57d6d306b1f787865043d60129 ]
This fixes:
net/mac80211/mesh_hwmp.c:603:26: warning: ‘target_metric’ may be used uninitialized in this function
target_metric is only consumed when reply = true so no bug exists here, but not all versions of gcc realize it. Initialize to 0 to remove the warning.
