irq/matrix: Fix memory overallocation
IRQ_MATRIX_SIZE is the number of longs needed for a bitmap, multiplied by the size of a long, yielding a byte count. But it is used to size an array of longs, which is way more memory than is needed. Change IRQ_MATRIX_SIZE so it is just the number of longs needed and the arrays come out the correct size.
