soc/amd/common/block/acpi/bert: fix NULL check

In acpi_soc_get_bert_region after the bert_errors_region call is was
checked if the region parameter is NULL after the call; since region is
a parameter of acpi_soc_get_bert_region, it's non-NULL. What we should
be checking here is if region points to a non-NULL pointer.
