EDAC/amd64: Check return value of amd_smn_read()
Check the return value of amd_smn_read() before saving a value. This
ensures invalid values aren't saved. The struct umc instance is
initialized to 0 during memory allocation. Therefore, a bad read will
keep the value as 0 providing the expected Read-as-Zero behavior.
