[PATCH 1/2] dmi-id: don't free dev structure after calling device_register

[Allen Hung]

dmi_dev is freed in error exit code but, according to the document
of device_register, it should never directly free device structure
after calling this function, even if it returned an error! Use
put_device() instead.
