iwlwifi: support host command with copied data
In addition to the NOCOPY flag, add a DUP flag that
tells the transport to kmemdup() the buffer and free
it after the command completes.
Currently this is only supported for a single buffer
in a given command, but that could be extended if it
should be needed.
