Prior to looking up a volume in the vldb the cm_volume_t
object is constructed.  If the response is VL_NOENT the
cm_volume_t object should be removed and place at the
head of the recycling list so that we do not recycle
something we might actually care about.

Convert more cm_volumeLock holds to read locks now
that we are using Interlocked operations to manipulate
the reference counts.
