genirq/irqdesc: Fix double increment in alloc_descs()
The recent rework of alloc_descs() introduced a double increment of the
loop counter. As a consequence only every second affinity mask is
validated.
Remove it.
[ tglx: Massaged changelog ]
Fixes: c410abbbacb9 ("genirq/affinity: Add is_managed to struct irq_affinity_desc")
