Alexander Shishkin 092f47c383 intel_th: msu: Preserve pre-existing buffer configuration
The MSU configuration registers may contain buffer address/size set by
the BIOS or an external hardware debugger, which may want to take over
tracing from the driver when the driver is not actively tracing.

Preserve these settings when not actively tracing.
