[PATCH v3 15/23] docs: translations: zn_CN: irq-affinity.rst: add a missing extension

[Mauro Carvalho Chehab]

Without .rst extension, ./scripts/documentation-file-ref-check will produce
a warning, and auto-generating cross-references by automarkup.py may not
work.

Fixes: 8137a49e1567 ("docs/zh_CN: Modify the translator tag and fix the wrong word")
