platform/x86: dell-smbios: Fix error path in dell_smbios_init()
In case of error in build_tokens_sysfs(), all the memory that has been
allocated is freed at end of this function. But then free_group() is
called which performs memory deallocation again.

Also, instead of free_group() call, there should be exit_dell_smbios_smm()
and exit_dell_smbios_wmi() calls, since there is initialization, but there
is no release of resources in case of an error.

Fix these issues by replacing free_group() call with
exit_dell_smbios_wmi() and exit_dell_smbios_smm().

Found by Linux Verification Center (linuxtesting.org) with SVACE.
