amd64_edac: fix ecc_enable_override handling
amd64_check_ecc_enabled() returns non-zero status when ECC checking/correcting is disabled and this fails further loading of the driver even when 'ecc_enable_override' boot param is used. Fix that by clearing return status in that case. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
