Reduce the lernel log level to KERN_NOTICE for messages related
to a missing caching mode page.
Reasons why I think this change is justified:
- The condition is not an error; the existing workaround of assuming
a write through cache doesn't limit functionality in any way.
- It doesn't warrant a warning either: as it is most likely
a hardware limitation, there is little that an ordinary user can do
about it besides replacing the affected hardware.
Making it a warning would still break quiet boot (kernel commandline
parameter 'quiet'), and may still trip log monitoring software
unneccessarily, either on every boot or whenever an affected
external device is plugged in.
- It should be a notice, for it is a normal but significant condition,
as it may impact write performance. This would bring it on par with
the log messages in the same function.
