Keep control in the NVMe driver instead of going through an indirect call back into ->revalidate_disk. Also reorder the function a bit to be easier to follow with the additional code. And now that we have removed all callers of revalidate_disk() in the nvme code, ->revalidate_disk is only called from the open code when first opening the device. Which is of course totally pointless as we have a valid size since the initial scan, and will get an updated view through the asynchronous notifiation everytime the size changes.
