Subject: [PATCH 5.19 0850/1157] USB: serial: fix tty-port initialized comments

[ Upstream commit 688ee1d1785c1359f9040f615dd8e6054962bce2 ]

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

Fixes: d41861ca19c9 ("tty: Replace ASYNC_INITIALIZED bit and update atomically")
