drbd: describe bitmap locking for bulk operation in finer detail
Now that we do no longer in-place endian-swap the bitmap, we allow selected bitmap operations (testing bits, sometimes even settting bits) during some bulk operations. This caused us to hit a lot of FIXME asserts similar to FIXME asender in drbd_bm_count_bits, bitmap locked for 'write from resync_finished' by worker Which now is nonsense: looking at the bitmap is perfectly legal as long as it is not being resized. This cosmetic patch defines some flags to describe expectations in finer detail, so the asserts in e.g. bm_change_bits_to() can be skipped if appropriate.
