From: Zeng Chi <redacted>

The function mlx5_esw_vport_vhca_id() is declared to return bool,
but returns -EOPNOTSUPP (-45), which is an int error code. This
causes a signedness bug as reported by smatch.

This patch fixes this smatch report:
drivers/net/ethernet/mellanox/mlx5/core/eswitch.h:981 mlx5_esw_vport_vhca_id()
warn: signedness bug returning '(-45)'
