[PULL 3/6] hw/nvme: fix example serial in documentation

[Klaus Jensen]

From: Niklas Cassel <niklas.cassel@wdc.com>

The serial prop on the controller is actually describing the nvme
subsystem serial, which has to be identical for all controllers within
the same nvme subsystem.

This is enforced since commit a859eb9f8f64 ("hw/nvme: enforce common
serial per subsystem").

Fix the documentation, so that people copying the qemu command line
example won't get an error on qemu start.

 This will create an NVM subsystem with two controllers. Having controllers
 linked to an ``nvme-subsys`` device allows additional ``nvme-ns`` parameters:
