[ofa-general] [PATCH] libibverbs: initialize qp state to RESET at qp creation time

[Jack Morgenstein]

Roland, libmlx4 commit af7707cecdfd5ca8a38b4d855070ebfc310a339f
(Initialize send queue entry ownership bits) is broken without
the fix below.  Since qp state is uninitialized, mlx4_qp_init_sq_ownership()
frequently ends up not being invoked.

Must initialize qp state to RESET at qp creation time.
