[i-g-t,v2,03/16] tests/core_hotunplug: Consolidate duplicated debug messages

Commit Message

Janusz Krzysztofik Aug. 7, 2020, 9:19 a.m. UTC

Some debug messages which designate specific test operations, or their
greater parts at least, sound always the same, no matter which subtest
they are called from.  Emit them, possibly updated with subtest
specified modifiers, from inside respective helpers instead of
duplicating them in subtest bodies.

v2: Rebase on current upstream master.
