Subject: [PATCH] firmware: log names of loaded firmware

It's non-trivial to figure out names of firmware that was actually
loaded, add a print statement at the end of _request_firmware that logs
the name & result of each firmware.

This is esp. valuable early in boot, before logging of UEVENT is
available.
