selftests: net: ksft: print more of the stack for checks
Print more stack frames and the failing line when check fails.
This helps when tests use helpers to do the checks.
Before:
# At ./ksft/drivers/net/hw/rss_ctx.py line 92:
# Check failed 1037698 >= 396893.0 traffic on other queues:[344612, 462380, 233020, 449174, 342298]
not ok 8 rss_ctx.test_rss_context_queue_reconfigure
After:
# Check| At ./ksft/drivers/net/hw/rss_ctx.py, line 387, in test_rss_context_queue_reconfigure:
# Check| test_rss_queue_reconfigure(cfg, main_ctx=False)
# Check| At ./ksft/drivers/net/hw/rss_ctx.py, line 230, in test_rss_queue_reconfigure:
# Check| _send_traffic_check(cfg, port, ctx_ref, { 'target': (0, 3),
# Check| At ./ksft/drivers/net/hw/rss_ctx.py, line 92, in _send_traffic_check:
# Check| ksft_lt(sum(cnts[i] for i in params['noise']), directed / 2,
# Check failed 1045235 >= 405823.5 traffic on other queues (context 1)':[460068, 351995, 565970, 351579, 127270]
