ACPI: fix sonypi ACPI driver registration to unregister on failure
Remove the assumption that acpi_bus_register_driver() returns the number of
devices claimed. Returning the count is unreliable because devices may be
hot-plugged in the future (admittedly not applicable for this driver).
This also fixes a bug: if sonypi_acpi_driver was registered but found no
devices, sonypi_exit() did not unregister it.
