nvme-pci: fix error handling in nvme_pci_enable()

There are two issues in nvme_pci_enable():

 1) If pci_alloc_irq_vectors() fails, device is left enabled. Fix this by
    adding a goto disable statement.
 2) nvme_pci_configure_admin_queue could return -ENODEV, in this case,
    we will need to free IRQ properly.  Otherwise the following warning
    could be triggered:
