Mario Limonciello 4d395c5e74 thunderbolt: Fix possible NULL pointer dereference in tb_acpi_add_link() 
When we walk up the device hierarchy in tb_acpi_add_link() make sure we
break the loop if the device has no parent. Otherwise we may crash the
kernel by dereferencing a NULL pointer.

Fixes: b2be2b05cf3b ("thunderbolt: Create device links from ACPI description")
