ACPI / device_sysfs: Change _SUN and _STA show functions error return to EIO
The error return from a sysfs show function is passed up through
the call chain and visible as the return from the read system call.
The show functions for the _STA and _SUN object currently return
-ENODEV. This patch changes the return to -EIO. ENODEV makes less
sense since the "device' exists or there wouldn't be a sysfs file.
