Log message:
Prevent a vmm(4) vcpu getting stuck if copyin(9) fails.
The VMM_IOC_RUN handler performed copyin after toggling the vcpu
state to running and didn't properly reset it if copyin fails. This
would prevent any subsequent attempt by a caller to issue VMM_IOC_RUN
for the vcpu.
Instead of adding complexity to the error handling path, perform
the copyin first before toggling the state.
