NVMe: Time out initialisation after a few seconds

THe device reports (in its capability register) how long it will take
to initialise.  If that time elapses before the ready bit becomes set,
conclude the device is broken and refuse to initialise it.  Log a nice
error message so the user knows why we did nothing.
