APEI: GHES: correctly return NULL for ghes_get_devices()
Since 315bada690e0 ("EDAC: Check for GHES preference in the
chipset-specific EDAC drivers"), vendor specific EDAC driver will not
probe correctly when CONFIG_ACPI_APEI_GHES is enabled but no GHES device
is present. Make ghes_get_devices() return NULL when the GHES device
list is empty to fix the problem.
Fixes: 9057a3f7ac36 ("EDAC/ghes: Prepare to make ghes_edac a proper module")
