[PATCH v2 0/3] NVMe PCI endpoint target fixes

[Damien Le Moal]

Two bug fix patch and one cleanup patch in this series.

The first patch fixes an issue with completion queue entries
initialization in the case of failed commands.

The second patch fixes
the initialization of the CC register to ensure that we can always
detect that the host is attempting to enable the controller (with
CC.EN).

The last patch cleans up/simplifies the management of the PCI link
state.

Changes from v1:
 - Patch 1: Add comments explaining iwhy the cqe needs to be initialized
   and also add setting the cqe sq_head field.
 - Fixed typos in patch 2 commit message
 - Added review tags to patch 3

Damien Le Moal (3):
  nvmet: pci-epf: Always fully initialize completion entries
  nvmet: pci-epf: Clear CC and CSTS when disabling the controller
  nvmet: pci-epf: Cleanup link state management
