arch/x86/acpi_bert_storage.c: Fix coverity error CID 1395706

There are 8 possible BERT context errors, with table ctx_names being a
table to print their names. Thus the table is supposed to have 8 elements,
and indeed it has 8 lines... but some lines are missing commas, and when
compiling it becomes a 5 element table. Add the commas at the appropriate
places.

BUG=b:115719190
TEST=none.
