Log Message:
rump: Set up the softint CPU bouncer only once, not once per CPU.

This is used for softint_schedule_cpu to schedule softints on other
CPUs.  There is one global lock, and one global condition variable,
and really there only needs to be one thread to handle the requests.
Without this change, we reinitialize the lock and condition variable,
leaking them (and possibly leave some threads confused if they are
currently taking the lock or waiting on the condition variable as
they get reinitialized).

Leak found by lsan while investigating:
