firewire: core: fix card->reset_jiffies overflow
On a 32-bit machine with, e.g., HZ=1000, jiffies will overflow after
about 50 days, so if there are between 25 and 50 days between bus
resets, the card->reset_jiffies comparisons can get wrong results.
To fix this, ensure that this timestamp always uses 64 bits.
