The "misc" terminology doesn't clearly explain what we intend to cover
in this phase. The only thing we do in there apart from FW fetch is
initializing the log workqueue, with the latter being required only in
the very rare case where we enable the log relay. To clean this up, we
can move the wq init to when the relay is enabled and rename the
function to clarify that they only fetch/release the blobs.
v2: only create log wq when needed (Michal), reword commit msg
accordingly

Commit message needs fixup, as now wq is already gone; with that,
