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.
