From: Michael Baum:
> The mlx5_vdpa_event_qp_create function makes shifting to the numeric
> constant 1, then multiplies it by another constant and finally assigns it into a
> uint64_t variable.
>
> The numeric constant type is an int with a 32-bit sign. if after shifting , its MSB
> (bit of sign) will change, the uint64 variable will get into it a different value
> than what the function intended it to get.
>
> Set the numeric constant 1 to be uint64_t in the first place.
