platform/x86: panasonic-laptop: Fix sysfs group leak in error path

Browse source

[ Upstream commit 43b0b7eff4 ]

The acpi_pcc_hotkey_add() error path leaks sysfs group pcc_attr_group
if platform_device_register_simple() fails for the "panasonic" platform
device.

Address this by making it call sysfs_remove_group() in that case for
the group in question.
