Checking recent upstream fastboot implementation [1], I can see [2] that
returning success or failure on calling 'partition-type:<part-name>'
makes an impact on the internal fastboot code paths, so unfortunately
I have to NAK my own patch. One idea could be calling fastboot_fail()
(not fastboot_okay as this patch proposed) with an updated error
message. Please, skip the patch for now.
