s390/sclp_sdias: Add missing break and "fall through"
If the last block of the HSA is read, EVSTATE_ALL_STORED is returned
by SCLP. Because of a missing break in the switch statement two trace
entries are written in this case: "all stored" and "part stored".
This patch adds the missing break and also adds a "fall through"
comment to improve the readability.
