firewire: ohci: fix PHY reg access after card ejection
Detect and handle ejection of FireWire CardBus cards in PHY register
accesses:
- The last attempt of firewire-core to reset the bus during shutdown
caused a spurious "firewire_ohci: failed to write phy reg" error
message in the log. Skip this message as well as the prior retry
loop that needlessly took 100 milliseconds.
- In the unlikely case that a PHY register was read right after card
ejection, a bogus value was obtained and possibly acted upon.
Instead, fail the read attempt.
