qemu: Temporarily disable metadata locking

Browse Source 
Turns out, there are couple of bugs that prevent this feature
from being operational. Given how close to the release we are
disable the feature temporarily. Hopefully, it can be enabled
back after all the bugs are fixed.

#lock_manager = "lockd"
# To serialize two or more daemons trying to change metadata on a
# file (e.g. a file on NFS share), libvirt offers a locking
# mechanism. Currently, only "lockd" is supported (or no locking
# at all if unset). Note that this is independent of lock_manager
# described above.
#
#metadata_lock_manager = "lockd"
# Set limit of maximum APIs queued on one domain. All other APIs
# over this threshold will fail on acquiring job lock. Specially,
# setting to zero turns this feature off.
