nvme: only set reserved_tags in nvme_alloc_io_tag_set for fabrics controllers
[ Upstream commit b794d1c2ad6d7921f2867ce393815ad31b5b5a83 ]
The reserved_tags are only needed for fabrics controllers. Right now only
fabrics drivers call this helper, so this is harmless, but we'll use it
in the PCIe driver soon.
