The driver currently uses a macro to decide whether we should use
NON_Q_VECTORS_PF or NON_Q_VECTORS_VF.

However, we also define NON_Q_VECTORS_VF to the same value as
NON_Q_VECTORS_PF. This means that the macro NON_Q_VECTORS(hw) will
always return the same value.

Let's just remove this macro, and replace it directly with an enum value
on the enum non_q_vectors.

This was detected by cppcheck and fixes the following warnings when
building with BUILD=KERNEL

[fm10k_ethtool.c:1123]: (style) Same value in both branches of ternary
operator.

[fm10k_ethtool.c:1142]: (style) Same value in both branches of ternary
operator.

[fm10k_main.c:1826]: (style) Same value in both branches of ternary
operator.

[fm10k_main.c:1849]: (style) Same value in both branches of ternary
operator.

[fm10k_main.c:1858]: (style) Same value in both branches of ternary
operator.

[fm10k_pci.c:901]: (style) Same value in both branches of ternary
operator.

[fm10k_pci.c:1040]: (style) Same value in both branches of ternary
operator.

[fm10k_pci.c:1726]: (style) Same value in both branches of ternary
operator.

[fm10k_pci.c:1763]: (style) Same value in both branches of ternary
operator.
