s390/sclp: Suppress unnecessary Store Data warning

Browse source

On systems that do not support Store Data events (such as when running
as KVM guest) the following warning message appears during boot:

 sclp_sd: Store Data request failed (eq=2, di=3, response=0x40f0,
          flags=0x00, status=0, rc=-5)

This warning does not add any useful information since the result is
expected due to missing support for that event type.

Suppress this message by checking the associated masks of supported
events before issuing a Store Data event.
