firewire: avoid memleak after phy config transmit failure
Use only statically allocated data for PHY config packet transmission.
With the previous incarnation, some data wouldn't be freed if the packet
transmit callback was never called.
A theoretical drawback now is that, in PCs with more than one card,
card A may complete() for a waiter on card B. But this is highly
unlikely and its impact not serious. Bus manager B may reset bus B
before the PHY config went out, but the next phy config on B should be
fine. However, with a timeout of 100ms, this situation is close to
impossible.
