I think I would really prefer things if we got rid of this wrapper. The
mlx4_bitmap stuff is really there to handle the case where we want to
have a mask and have the non-used bits cycle to avoid reusing QPN etc.
If we have a bitmap with no mask that's no a power of 2 in size, there's
really no value in the mlx4 wrapper -- we might as well just allocate a
bitmap directly.
And since this is only used in one place (for the EQ tables) I think it
makes sense to just open-code everything in the EQ code.
