Revert adding the packed attribute, as it really doesn't make sense why that

would do any good.  Fix the real bug, which is to do the check to see if the
frame came from a translator at the beginning of ast_frame_free(), instead of
at the end.  This ensures that it always gets checked, even if none of the
parts of the frame are malloc'd, and also ensures that we aren't looking at
free'd memory in the case that it is a malloc'd frame.

(closes issue #11792, reported by explidous, patched by me)
