platform/x86: panasonic-laptop: Fix OPTD notifier registration and cleanup

An ACPI notify handler is leaked if device_create_file() returns an
error in acpi_pcc_hotkey_add().

Also, it is pointless to call pcc_unregister_optd_notifier() in
acpi_pcc_hotkey_remove() if pcc->platform is NULL and it is better
to arrange the cleanup code in that function in the same order as
the rollback code in acpi_pcc_hotkey_add().

Address the above by placing the pcc_register_optd_notifier() call in
acpi_pcc_hotkey_add() after the device_create_file() return value
check and placing the pcc_unregister_optd_notifier() call in
acpi_pcc_hotkey_remove() right before the device_remove_file() call.
