diameter_tcp.erl:575: Function l/2 has no local return

Appears to have introduced in commit eb69b55b, which cleaned up after a
functional change in commit 2afd1fe5, after which there was no longer
any l/2 clause that returned.

Why functions explicitly exit rather than return a stop tuple to have
gen_server exit is a bit of a mystery, but it was probably just
consistency given other usage in the module. There's no functional
difference.
