ixgbe: move v_idx into q_vector and use as index only
The v_idx value was being used as both a bitmask and an index. This change makes it so that the q_vector contains the index and allows for much of the code to be simplified since disabling a q_vector involves only clearing one bit in the interrupt bitmask.
