tests: Fix `check_ping` function in test_bgp_srv6l3vpn_to_bgp_vrf.py

The check_ping function `_check` function was asserting and being
passed to the topotests.run_and_expect() functionality causing
it to not run the full range of pings if one failed the test.

So effectively it was properly detecting pass / failure but
only allowing for 1 iteration if it was going to fail.

Modify the code to not assert and act like all the other
run_and_expect functionality.
