rbd: remove unused constants and fields

RBDAIOCB.status was only used for cancel, which was removed in
7691e24dbebb46658e89b3f950fda6ec78bbb823.

RBDAIOCB.sector_num was never used.

RADOSCB.done and rcbid were never used.

RBD_FD* are obsolete since the pipe was removed in
e04fb07fd1676e9facd7f3f878c1bbe03bccd26b.
