firewire: core: correct comment about execution context
The comment for fw_address_callback_t describes the execution context,
but the callback has not been called from RCU read-side critical section
since v6.17.
Fixes: e884a8a0c573 ("firewire: core: call FCP address handlers outside RCU read-side critical section")
Fixes: e8cf6875005b ("firewire: core: call handler for exclusive regions outside RCU read-side critical section")
