hw/cxl: avoid build error with lower(<=9) gcc versions

[Jeongtae Park <jtp.park@samsung.com>]

We are testing on the below branch[1] and getting the following build
error when using gcc-9 or gcc-7 (gcc-11 is ok).

I was reported in private to Jonathan Cameron, and he will get rid of
it soon.

This is just for your information and for keeping on list.

Thanks
