When a test returns -EAGAIN this should not be considered a failure. Fix what seems to be a problem case, where the pytests see a failure when a test has merely been skipped.
We cannot squash the -EAGAIN error in ut_run_test() since the failure count is incremented by its caller, ut_run_test_live_flat()
The specific example here is on snow, where a test is compiled into the image but cannot run, so returns -EAGAIN to skip:
test/py/tests/test_ut.py sssnow # ut bdinfo bdinfo_test_eth Test: bdinfo_test_eth: bdinfo.c Skipping: Console recording disabled test/test-main.c:486, ut_run_test_live_flat(): 0 == ut_run_test(uts, test, test->name): Expected 0x0 (0), got 0xfffffff5 (-11) Test bdinfo_test_eth failed 1 times Skipped: 1, Failures: 1 snow # F+u-boot-test-reset snow snow
The fix is simply to respect the return code from ut_run_test(), so do that.
