Henrique de Moraes Holschuh ac36393de6 ACPI: thinkpad-acpi: fix the module init failure path
Thomas Renninger reports that if one tries to load thinkpad-acpi in a
non-thinkpad, one gets:

Call Trace:
 [<ffffffff802fa57d>] kref_get+0x2f/0x36
 [<ffffffff802f97f7>] kobject_get+0x12/0x17

 [<ffffffff8020bc2e>] system_call+0x7e/0x83

So, track if the platform driver and its driver attributes were registered,
and only deallocate them in that case.

This patch is based on Thomas Renninger's patch for the issue.
