Subject: [PATCH v2 2/2] platform/x86: dell-smbios: Simplify error handling

When the allocation of value_name fails, the error handling code
uses two gotos for error handling, which is not necessary.

Simplify the error handling in this case by only using a single goto.

Tested on a Dell Inspiron 3505.
