[PATCH iproute2] vrf: Add support for table names

[David Ahern]

Currently, the table id for VRF devices requires an integer. Convert
it to use rtnl_rttable_a2n which handles table names from the iproute2
directory.

This also fixes a bug in the original commit where table name are not
properly handled.
