Intel CAVS: log missing of tests/lib/p4workq/

[LixinGuoX]

Describe the bug
tests/lib/p4workq/ has 4 test functions

test_p4wq_simple
test_resubmit
test_fill_queue
test_stress

On Intel CAVS platform, we lost the log of test_resubmit and test_fill_queue

To Reproduce
Steps to reproduce the behavior:

1. twister -W -p intel_adsp_cavs15 --device-testing --device-serial-pty=$HOME/zephyrproject/zephyr/soc/xtensa/intel_adsp/tools/cavstwist.sh --west-flash=$HOME/zephyrproject/zephyr/soc/xtensa/intel_adsp/tools/cavstwist.sh -T tests/lib/p4workq/ -vv

Expected behavior
We should have intact log of test functions.

the warning log message above is flooding the buffer, if you remove it, you get the expected output, this is the same bug we have seen before with the memory window not able to handle message floods...

not related to twister, it is a logging backend issue of ADSP.
