Series tests/core_hotunplug: New subtests and enhancements | expand

Commit Message

The purpose of debug messages displayed by the test is to make
identification of a subtest phase that fails more easy.  Since issues
exhibited by the test are mostly reported to dmesg, print those debug
messages to /dev/kmsg as well.
