Subject: [PATCH] nvme: Mark external NVMe devices as removable
Commit c037b6c818c3 ("PCI: Add sysfs "removable" attribute") can mark
entire Thunderbolt hierarchy as removable, if system firmware provides
correct attribute.
So apply GENHD_FL_REMOVABLE for NVMe if removable bit is set, to make
userspace daemon like Udisks knows it can be automount.
