[PATCH] plugin/lm: avoid closing migration-send input twice

lm_migration_send() declares the input stream with __cleanup_file, which
closes the stream automatically when the function returns. The function
also calls fclose() explicitly after fread() without clearing the
pointer.

The cleanup handler consequently closes the same stream again, causing
glibc to abort with:

    free(): double free detected in tcache 2

Remove the explicit fclose() and let __cleanup_file close the stream.

Fixes: 6d2a869dd054 ("plugin/lm: Introduce Live Migration plugin")
