Subject: [ 100/171] libceph: provide osd number when creating osd

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

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

From: Alex Elder <elder@...tank.com>

(cherry picked from commit e10006f807ffc4d5b1d861305d18d9e8145891ca)

Pass the osd number to the create_osd() routine, and move the
initialization of fields that depend on it therein.
