sys/dev/vmm : vmm.c vmm.h
Log message:
Fix race in vmm(4) vm termination path.
Two callers can enter vm_terminate simultaneously and race to remove
the vm from the SLIST and teardown the vm. This adds a flag to the
vm struct and uses atomic cas operations to only have one caller
advance while the other callers receive EBUSY.
