can: gw: use call_rcu() instead of costly synchronize_rcu()
Commit fb8696ab14ad ("can: gw: synchronize rcu operations
before removing gw job entry") added three synchronize_rcu() calls
to make sure one rcu grace period was observed before freeing
a "struct cgw_job" (which are tiny objects).
This should be converted to call_rcu() to avoid adding delays
in device / network dismantles.
Use the rcu_head that was already in struct cgw_job,
not yet used.
