vhost: fix vm_wait_for_boot arg check.

Browse Source 
This was changed recently to enable a shell coding style checker, but $*
does not represent the number of arguments supplied to the function,
rather it is an alternative version of $@ that stores all arguments in a
single string. So we should be checking against an empty string and not
0.

By checking against 0, every time we passed 0 into vm_wait_for_boot, we
tried booting every vm in that directory. This causes errors on nightly
tests and intermittent failures during per-patch testing.
