NVMe: Merge issue on character device bring-up
A recent patch made it possible to bring up the character handle when the device is responsive but not accepting a set-features command. Another recent patch moved the initialization that requires we move where the checks for this condition occur. This patch merges these two ideas so it works much as before.
