[ Upstream commit a5f622984a623df9a84cf43f6b098d8dd76fbe05 ]
A couple of tests are verifying a route has been removed. The helper expects the prefix as the first part of the expected output. When checking that a route has been deleted the prefix is empty leading to an invalid ip command:
$ ip ro ls match Command line is not complete. Try option "help"
Fix by moving the comparison of expected output and output to a new function that is used by both check_route and check_route6. Use the new helper for the 2 checks on route removal.
Also, remove the reset of 'set -x' in route_setup which overrides the user managed setting.
