- fix typ0 in message: NLSMG -> NLMSG
- use strerror() to print a human readable message
- don't print error message if error is ENETUNREACH: it means no route
found
Signed-off-by: Antonio Quartulli <a...@unstable.cc>

v2:
- change %d to %s (thanks Michael Shiels for catching this)
v3:
- don't print error when ENETUNREACH is returned
v4:
- put { } around if block
