netdevsim: allow normal queue reset while down

Resetting queues while the device is down should be legal.
Allow it, test it. Ideally we'd test this with a real device
supporting devmem but I don't have access to such devices.

Test listing netdevsim NAPIs before and after a single queue
has been reset (and NAPIs re-added).

Start from resetting the middle queue because edge cases
(first / last) may actually be less likely to trigger bugs.

selftests: net: set the exit code correctly in Python tests

Test cases need to exit with non-zero status if they failed,
we currently don't do that:

# KTAP version 1
# 1..3
# # At /root/ksft-net-drv/drivers/net/./ping.py line 18:
# # Check failed 1 != 2
# not ok 1 ping.test_v4

# ok 3 ping.test_tcp
# # Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: ping.py
^^^^

It's a bit tempting to make the exit part of ksft_run(),
but that only works well for very trivial setups. We can
revisit this later, if people forget to call ksft_exit().
