[PATCH v2] Revert "nvme: Add quirk for Kingston NVME SSD running FW E8FK11.T"

[Jian-Hong Pan]

Since commit 253eaf4faaaa ("PCI/MSI: Fix incorrect MSI-X masking on
resume") is merged, we can revert the previous quirk now.

This reverts commit 19ea025e1d28c629b369c3532a85b3df478cc5c6.

253eaf4faaaa is pending on my pci/msi branch, planned to be merged
during the v5.5 merge window.

This revert patch must not be merged before 253eaf4faaaa.  The easiest
way to do that would be for me to merge this one as well; otherwise
we have to try to make things happen in the right order during the
merge window.

If the NVMe folks ack this idea and the patch, I'd be happy to merge
it.

OK, I'll ask Linus to merge this revert after my main PCI pull request
for v5.5-rc1.
