nvmet: pci-epf: clear completion queue IRQ flag on delete

The function nvmet_pci_epf_delete_cq() unconditionally calls
nvmet_pci_epf_remove_irq_vector() even for completion queues that do not
have interrupts enabled. Furthermore, for completion queues that do
have IRQ enabled, deleting and re-creating the completion queue leaves
the flag NVMET_PCI_EPF_Q_IRQ_ENABLED set, even if the completion queue
is being re-created with IRQ disabled.

Fix these issues by calling nvmet_pci_epf_remove_irq_vector() only if
NVMET_PCI_EPF_Q_IRQ_ENABLED is set and make sure to always clear that
flag.
