nvme: ensure subsystem reset is single threaded commit 1e866afd4bcdd01a70a5eddb4371158d3035ce03 upstream. The subsystem reset writes to a register, so we have to ensure the device state is capable of handling that otherwise the driver may access unmapped registers. Use the state machine to ensure the subsystem reset doesn't try to write registers on a device already undergoing this type of reset.
