nvme initialize core quirks before calling nvme_init_subsystem

A device might have a core quirk for NVME_QUIRK_IGNORE_DEV_SUBNQN
(such as Samsung X5) but it would still give a:

    "missing or invalid SUBNQN field"

warning as core quirks are filled after calling nvme_init_subnqn.  Fill
ctrl->quirks from struct core_quirks before calling nvme_init_subsystem
to fix this.

Tested on a Samsung X5.
