net/mlx4_core: Fix wrong mask and error flow for the update-qp command
The bit mask for currently supported driver features (MLX4_UPDATE_QP_SUPPORTED_ATTRS)
of the update-qp command was defined twice (using enum value and pre-processor
define directive) and wrong.
The return value of the call to mlx4_update_qp() from within the SRIOV
resource-tracker was wrongly voided down.
Fix both issues.
issue: none
Fixes: 09e05c3f78e9 ('net/mlx4: Set vlan stripping policy by the right command')
Fixes: ce8d9e0d6746 ('net/mlx4_core: Add UPDATE_QP SRIOV wrapper support')
