ipmi: fix broken asset tag function

The Asset Tag command was implemented via
https://github.com/openbmc/openbmc/commit/8af3309b, but broke via
https://github.com/openbmc/openbmc/commit/b1009126. The latter commit
did do the right thing though, the former commit had to use an append
operator instead of a weak default value, when specifying a value other
than "". The weak default value will not be set at all, when a
previously assigned value is found.

Resolves openbmc/openbmc#2867.
