With the addition of erasure coding support in the future, scratch variable-length array in crush_do_rule_ary() is going to grow to at least 200 bytes on average, on top of another 128 bytes consumed by rawosd/osd arrays in the call chain. Replace it with a buffer inside struct osdmap and a mutex. This shouldn't result in any contention, because all osd requests were already serialized by request_mutex at that point; the only unlocked caller was ceph_ioctl_get_dataloc().
