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.
Fixes: 2f75d9e1c905 ("genirq: Implement bitmap matrix allocator")
