firewire: core: fix race condition against transaction list

In the Linux kernel, the following vulnerability has been resolved:

firewire: core: fix race condition against transaction list

The list of transaction is enumerated without acquiring card lock when

expiration into the scope of lock. The value of jiffies in card structure
is referred before acquiring the lock.
