[PATCH] iface-modem: free GError when interface initialization is cancelled

[Ben Chan]

This patch fixes an assertion failure 'ctx->fatal_error == NULL' in
initialization_context_complete_and_free(), which happens if
'fatal_error' of the initialization context is set during the modem
interface initialization and the initialization is later cancelled.
