init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems
where the Dell WMI interface is supported. While exit_dell_smbios_wmi()
unregisters it unconditionally, this leads to the following oops:
[ 175.722921] ------------[ cut here ]------------
[ 175.722925] Unexpected driver unregister!
[ 175.722939] WARNING: CPU: 1 PID: 3630 at drivers/base/driver.c:194 driver_unregister+0x38/0x40

[ 175.723089] Call Trace:

[ 175.723148] ---[ end trace 064c34e1ad49509d ]---
Make the unregister happen on the same condition the register happens
to fix this.
