Subject: [PATCH 3.18 078/145] libceph: use BUG() instead of BUG_ON(1)

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit d24cdcd3e40a6825135498e11c20c7976b9bf545 upstream.

I ran into this compile warning, which is the result of BUG_ON(1)
not always leading to the compiler treating the code path as
unreachable:

    include/linux/ceph/osdmap.h: In function 'ceph_can_shift_osds':
    include/linux/ceph/osdmap.h:62:1: error: control reaches end of non-void function [-Werror=return-type]

Using BUG() here avoids the warning.
