  From: Yuval Avnery <yuvalav@mellanox.com>

Added missing code to free Input/Output buffers and memory
registration.
Also added calls to this code in case of error in the qp setup
procedure.
The rollback code itself did not handle rollback properly
and did not check return value from the fastpath setup.
