LU-15724 osp: wakeup all precreate threads

Number of threads could sleep at osp_precreate_reserve() and
wait objects from OST. When MDT stops Lustre should wakeup
all threads. When opd_pre_recovering is set any wakeup of
opd_pre_user_waitq is useless. Failover of MDT does not produce
disconnect event, only inactive, so osp_precreate_cleanup_orphans()
can not be awakened.

LustreError: 0-0: Forced cleanup waiting for mdt-kjcf05-MDT0001_UUID
namespace with 46 resources in use, (rc=-110)
