USB: serial: fix tty-port initialized comments

Browse Source 
[ Upstream commit 688ee1d1785c1359f9040f615dd8e6054962bce2 ]

Fix up the tty-port initialized comments which got truncated and
obfuscated when replacing the old ASYNCB_INITIALIZED flag.

Fixes: d41861ca19 ("tty: Replace ASYNC_INITIALIZED bit and update atomically")
