Because for other failures, we don't know when the conditions
for them can be satisfied. For example, we don't know when the
memory allocation can be met for one previous allocation failure.

IMO, at least the approach provides one simple way to solve the
firmware loading problem during. early boot or resume

Looks there is no special requirement for the error handling of
request_firmware, just like other failures' handling, undo things
which has been done, isn't there?
