osd: improve OSD robustness.

Achieved by
1. osd superblock data is replicated in onode's OMAP - hence one can
   recover from that after onode's content is corrupted.
2. pg_num_history object gets full overwrite which eliminatess the need to
   merge with previous data (and hence reading corrupted data wouldn't
   kill OSD).
