Christophe JAILLET 89f5f8fb5b EDAC/thunderx: Remove irrelevant variable from error messages
'ret' is irrelevant (it is 0) for both dev_err() calls, so just remove
it from the error message.

Kees Cook 6663484b4e EDAC, thunderx: Remove VLA usage
In the quest to remove all stack VLA usage from the kernel[1], switch to
using a kmalloc-allocated buffer instead of stack space. This should be
fine since the existing routine is allocating memory too.
