platform/x86: dell-wmi-sysman: Fix release_attributes_data() getting …

…called twice on init_bios_attributes() failure

BugLink: https://bugs.launchpad.net/bugs/1931509

All calls of init_bios_attributes() will result in a
goto fail_create_group if they fail, which calls
release_attributes_data().

So there is no need to call release_attributes_data() from
init_bios_attributes() on failure itself.
