[PULL,02/32] block: Drop BDS comment regarding bdrv_append()

Commit Message

There is a comment above the BDS definition stating care must be taken
to consider handling newly added fields in bdrv_append().

Actually, this comment should have said "bdrv_swap()" as of 4ddc07cac
(nine years ago), and in any case, bdrv_swap() was dropped in
8e419aefa (six years ago).  So no such care is necessary anymore.
