net/mlx5e: Allow relaxed ordering over VFs

By PCI spec, the config space of the VF always report relaxed ordering
not supported while it inherits this property from its PF. Hence using
pcie_relaxed_ordering_enable(), always disables the relaxed ordering on
all VFs. Remove this check and rely on the firmware which queries the
config space of the PF and set the capability bit accordingly.
