ACPI: configfs: add missing check after configfs_register_default_group()
A list_add corruption is reported by Hulk Robot like this:
==============
list_add corruption.
Call Trace:
link_obj+0xc0/0x1c0
link_group+0x21/0x140
configfs_register_subsystem+0xdb/0x380
acpi_configfs_init+0x25/0x1000 [acpi_configfs]

load_module+0x35c8/0x4380
__do_sys_finit_module+0x10d/0x1a0
do_syscall_64+0x34/0x80
It's because of the missing check after configfs_register_default_group,
where configfs_unregister_subsystem should be called once failure.
Fixes: 612bd01fc6e0 ("ACPI: add support for loading SSDTs via configfs")
