VMCI: Fix some error handling paths in vmci_guest_probe_device()

VMCI: Fix some error handling paths in vmci_guest_probe_device()

BugLink: https://bugs.launchpad.net/bugs/1978145
The 'err_remove_vmci_dev_g' error label is not at the right place.
This could lead to un-released resource.

There is also a missing label. If pci_alloc_irq_vectors() fails, the
previous vmci_event_subscribe() call must be undone.
