[ Upstream commit 25e58af4be412d59e056da65cc1cefbd89185bd2 ]
The Intel P4500/P4600 SSDs do not report a subsystem NQN despite claiming
compliance to a standards version where reporting one is required.
Add the IGNORE_DEV_SUBNQN quirk to not fail the initialization of a
second such SSDs in a system.
