Subject: net/core: __hw_addr_create_ex does not initialize sync_cnt
X-Git-Tag: upstream/snapshot3+hdmi~4979^2~24

net/core: __hw_addr_create_ex does not initialize sync_cnt

The sync_cnt field is not being initialized, which can result
in arbitrary values in the field.  Fixed by initializing it to zero.
