W=1 build warns that peer_device is undocumented in the bitmap I/O
handlers. This parameter was introduced in commit 8164dd6c8ae1
("drbd: Add peer device parameter to whole-bitmap I/O handlers"), but
the kernel-doc was not updated.

Add the missing @peer_device entry.

Or just make it a non-kerneldoc comment as it doesn't document an
external API to start with.
