was broken by this commit:

https://mail-index.netbsd.org/source-changes/2020/05/30/msg117884.html
>How-To-Repeat:
I found that through code inspection
using the gem device over the pci bus on a machine where the MAC address comes from the extended ROM
>Fix:
the wrong buffer size( sizeof pointer) used when reading data through the pci bus. so we should use the right size.
