[ewg] [PATCH] libibverbs - return valid bad_wr from ibv_cmd_post_send()

[Ralph Campbell]

There are error cases in ib_uverbs_post_send() where the return
value is negative (i.e., an error) and yet a non-zero resp.bad_wr
is not written back to ibv_cmd_post_send().  In this case,
ibv_cmd_post_send() should still set the bad_wr pointer.

It seems to me that this should go into OFED 1.3.
I will leave the mechanics of how that happens to Roland and Vlad.
