[LU-13513] osp_precreate_reserve() should not take d->opd_pre_status == -EIO as fatal

Description

When OST_CREATE (not resendable rpc) sent by precreate thread fails
with network error, osp_pre_update_status() sets d->opd_pre_status to
EIO. osp_precreate_reserve() considers EIO as fatal and does not wait
for another attempt from precreate thread. That may make
mdt_intent_open to return ENOSPC confusing a caller.
ENOSPC comes from lod_alloc_rr().
