 Description   

on small devices (like used with local configuration) and ldiskfs ofd batched pre-creation can exceed transaction causing a lot of messages like:

Lustre: 13034:0:(osd_handler.c:697:osd_trans_start()) lustre-OST0000: too many transaction credits (3191 > 1024)
LustreError: 13034:0:(osd_handler.c:708:osd_trans_start()) attr_set: 0, punch: 0, xattr_set: 0,
LustreError: 13034:0:(osd_handler.c:711:osd_trans_start()) create: 127, ref_add: 0, ref_del: 0, write: 1
LustreError: 13034:0:(osd_handler.c:714:osd_trans_start()) insert: 0, delete: 0, destroy: 0

I think osd_trans_start() can return an error and then ofd_precreate_objects() can tune ofd_precreate_batch
