Fix double free for *modinfo with non '\0' terminated wrong
modules.builtin.modinfo, which is because EOF is minus value.

The function allocates array but on building it if get_string()
fails it returns the error leaving the array allocated. The caller
does not care about it in error case either.
Free it to fix memory leak.

The kernel since version v5.2-rc1 exports information about built-in
modules in the modules.builtin.modinfo. Information is stored in
the same format as in the separate modules (null-terminated string
array). The module name is a prefix for each line.
