A static checker gave the following warnings:
drivers/edac/sb_edac.c:1030 ibridge_get_ha() warn: signedness bug returning '(-22)'
drivers/edac/sb_edac.c:1037 knl_get_ha() warn: signedness bug returning '(-22)'
Both because the functions are declared to return a "u8", but try to
return -EINVAL for the error case.
Fix by returning 0xff (since the caller doesn't look at, or pass on, the
return value).
