kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()

A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...
