libceph: replace overzealous BUG_ON in osdmap_apply_incremental()

Browse source

commit e00c3f71b5 upstream.

If the osdmap is (maliciously) corrupted such that the incremental
osdmap epoch is different from what is expected, there is no need to
BUG.  Instead, just declare the incremental osdmap to be invalid.
