libceph: fix messenger CONFIG_BLOCK dependencies
The ceph messenger has a few spots that are only used when bio messages are supported, and that's only when CONFIG_BLOCK is defined. This surrounds a couple of spots with #ifdef's that would cause a problem if CONFIG_BLOCK were not present in the kernel configuration.
