Subject: iproute2: ip -force -batch does not continue on errors

Hallo,

Test szenario:

# cat b.txt
route del 1.2.3.0/24 dev eth0
route del 1.2.4.0/24 dev eth0
route del 1.2.5.0/24 dev eth0
route add 1.2.3.0/24 dev eth0

# ip -force -batch b.txt
RTNETLINK answers: No such process

Expectation: The three route del commands may fail if the route does 
not (yet) exist, and then (as I am using -force) the route add gets 
executed.

But instead the batch processing is aborted at the first failing "route 
del" command, forcing me to execute ip once per route del instead of 
using the batchmode.

Tested mainly using iproute2 3.16.0, but the current git tree seems to 
behave mostly the same, except that it only executes anything if I add 
"-f inet" to the commandline, otherwise it rejects the first line with 
'Error: an inet prefix is expected rather than "1.2.3.0/24".'
