libceph: allow addrvecs with a single NONE/blank address
Normally, an unused OSD id/slot is represented by an empty addrvec.
However, it also appears to be possible to generate an osdmap where
an unused OSD id/slot has an addrvec with a single blank address of
type NONE. Allow such addrvecs and make the end result be exactly
the same as for the empty addrvec case -- leave addr intact.
