devstat: Fix a kernel stack disclosureHEADmain

The 16-byte "device_name" field was not zero-filled, so could contain
uninitialized stack data.  Zero the whole struct, as that's the
prevailing pattern for this kind of conversion code, and it's more
robust in the face of future revisions to struct devstat.
