The solution is to kill spfs process before freezing attempt on fast stop
stage. And since the spfs pid in unknown, this is implemented by killing
container processes before freezing (error are not handled).

There could be a situation, when RPC task is not yet sleeping, but already
passed the check for "kill_tasks" in __rpc_execute().
There is a race in such a case, because task will fall into sleep anyway.
This patch makes this probability a little bit less.
