[PATCH v4 9/9] hw/nvme: Refer to dev->exp.sriov_pf.num_vfs

[Akihiko Odaki <akihiko.odaki@daynix.com>]

NumVFs may not equal to the current effective number of VFs because VF
Enable is cleared, NumVFs is set after VF Enable is set, or NumVFs is
greater than TotalVFs.

Fixes: 11871f53ef8e ("hw/nvme: Add support for the Virtualization Management command")
