xhci: dbgtty: fix device unregister: fixup
[ Upstream commit 74098cc06e753d3ffd8398b040a3a1dfb65260c0 ]
This fixup replaces tty_vhangup() call with call to
tty_port_tty_vhangup(). Both calls hangup tty device
synchronously however tty_port_tty_vhangup() increases
reference count during the hangup operation using
scoped_guard(tty_port_tty).
