Subject: rbd: Fix error recovery in rbd_obj_read_sync()
From: Jan Kara <jack@xxxxxxx>
commit a8d4205623ae965e36c68629db306ca0695a2771 upstream.
When we fail to allocate page vector in rbd_obj_read_sync() we just
basically ignore the problem and continue which will result in an oops
later. Fix the problem by returning proper error.
