[PATCH iproute2] ip: Fix batch processing

After the comment cited below, batch mode neglects to set the global
variable batch_mode to a non-zero value. Netns and VRF commands use this
variable, and break in batch mode. Fix by setting the value again.

Fixes: 1d9a81b8c9f3 ("Unify batch processing across tools")
