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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
