firewire: core: fix retries calculation in iso manage_channel()
If there is a permanent error condition when communicating with the IRM,
after the sixth error, the retry variable will be decremented to -1.
If, in this case, the bits in channels_mask are not yet exhausted, the
next channel is retried 2^32 times.
To fix this, check that retry is never decremented beyond zero.
