EDAC, sb_edac: Simplify switch statement
clang static analyzer reports this problem
sb_edac.c:959:2: warning: Undefined or garbage value
returned to caller
return type;
^~~~~~~~~~~
This is a false positive.
However by initializing the type to DEV_UNKNOWN the 3 case can be
removed from the switch, saving a comparison and jump.
