interconnect: debugfs: initialize src_node and dst_node to empty strings

In the Linux kernel, the following vulnerability has been resolved:

interconnect: debugfs: initialize src_node and dst_node to empty strings

The debugfs_create_str() API assumes that the string pointer is either NULL
or points to valid kmalloc() memory. Leaving the pointer uninitialized can
cause problems.

Initialize src_node and dst_node to empty strings before creating the
debugfs entries to guarantee that reads and writes are safe.
