[PATCH 16/22] qcow2: Mark check_constraints_on_bitmap() GRAPH_RDLOCK

[Kevin Wolf <kwolf@redhat.com>]

It still has an assume_graph_lock() call, but all of its callers are now
properly annotated to hold the graph lock. Update the function to be
GRAPH_RDLOCK as well and remove the assume_graph_lock().
