Fix the following kernel-doc warning reported by `scripts/kernel-doc`:

  WARNING: ./include/linux/irqdomain.h:59 struct member 'affinity' not described in 'irq_fwspec_info'

The field name in the comment block was documented as '@cpumask',
but the actual member is named 'affinity'. Update the kernel-doc
comment to match the structure definition.
