usb-serial: straighten out serial_open
This patch (as1291) removes a bunch of code from serial_open(), things
that were rendered unnecessary by earlier patches. A missing spinlock
is added to protect port->port.count, which needs to be incremented
even if the open fails but not if the tty has gotten a hangup. The
test for whether the hardware has been initialized, based on the use
count, is replaced by a more transparent test of the
ASYNCB_INITIALIZED bit in the port flags.
