ghes_edac: Use snprintf() to silence a static checker warning
My static checker complains because the "e->location" has up to 256
characters but we are copying it into the "pvt->detail_location" which
only has space for 240 characters. That's not counting the surrounding
text and the "e->other_detail" string which can be over 80 characters
long.
I am not familiar with this code but presumably it normally works.
Let's add a limit though for safety.
