A new __counted_by() attribute was introduced in [1]. It makes the
compiler's sanitizer aware of the actual size of a flexible array
member, allowing for additional runtime checks.
Move the end of line comments to the previous line to make room and
apply the __counted_by() attribute to the can flexible array member of
struct pciefd_board.
