ceph plugin: Use compound literals to initialize a VLA.

This also moves the DEBUG() statement before the sanity check in an
attempt to make scan-build happy: scan-build is under the impression
that the DEBUG() macro would write to the g_num_daemons global variable.

While we're at it, use PRIu32 to print the uint32_t.

Issue: #1835
