microcode: Use request_firmware_direct()

Use the new helper, request_firmware_direct(), for avoiding the
lengthy timeout of non-existing firmware loads.  Especially the Intel
microcode driver suffers from this problem because each CPU triggers
the f/w loading, thus it ends up taking (literally) hours with many
cores.
