[PATCH] devtools: fix version variable not initialized

[Dengdui Huang]

The version variable is not initialized. Therefore, if the -V option
is not specified, the value of $version is obtained from the context,
which may cause the version map parsing failure.

Fixes: 6edec7f202ac ("devtools: list symbols by version")
