Michael Kelley 0bbb8382db irq/matrix: Fix memory overallocation
[ Upstream commit 57f01796f14fecf00d330fe39c8d2477ced9cd79 ]

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: 2f75d9e1c9 ("genirq: Implement bitmap matrix allocator")
