[openib-general] [PATCH 4/7] libehca: Update to match new ibv_cmd_reg_mr() prototype

[Roland Dreier]

ibv_cmd_reg_mr() now takes extra parameters to allow low-level
drivers to pass back a response.  Add a test for the preprocessor
define IBV_CMD_REG_MR_HAS_RESP_PARAMS, and if it exists, have
libehca match the new prototype.
