[focal:linux-azure][PATCH 1/2] IB/mlx5: Align usage of QP1 create flags with rest of mlx5 defines

[Marcelo Henrique Cerri]

From: Michael Guralnik <michaelgur at mellanox.com>

BugLink: https://bugs.launchpad.net/bugs/1874503

There is little value in keeping separate function for one flag, provide
it directly like any other mlx5 define.
