ktls: start a thread to keep the 16k ktls buffer zone populated
My Cirrus-CI boot smoke test is now failing with:
Starting KTLS alloc thread for domain 0
panic: sleeping without a lock
cpuid = 0

I'd thought that I'd tested this with INVARIANTS, but I guess I was
wrong. The assert is failing because I'm sleeping forever (sbt == 0).
I don't understand the point of the assert, but I've
reproduced the panic and am testing a workaround.
