genirq/affinity: Take reserved vectors into account when spreading irqs
The recent addition of reserved vectors at the beginning or the end of the vector space did not take the reserved vectors at the beginning into account for the various loop exit conditions. As a consequence the last vectors of the spread area are not included into the spread algorithm and are treated like the reserved vectors at the end of the vector space and get the default affinity mask assigned. Sum up the affinity vectors and the reserved vectors at the beginning and use the sum as exit condition.
