It is normal to flush CQEs if the QP is in error state. Hence there's no
use in printing a message per CQE to dmesg.

Current code didn't modify the QP state to error because it queried the
QP state as a bitmap while it isn't. So the code never got executed.
This patch fixes this and queries for each QP state respectively and not
at once via a bitmask.

Add struct ib_udata to the signature of create_ah callback that is
implemented by IB device drivers. This allows HW drivers to return extra
data to the userspace library.
This patch prepares the ground for mlx5 driver to resolve destination
mac address for a given GID and return it to userspace.
