Johan Hovold f79b2d0fe8 USB: keyspan: fix NULL-pointer dereferences and memory leaks 
Fix NULL-pointer dereference at release by moving port data allocation
and deallocation to port_probe and port_remove.

Fix NULL-pointer dereference at disconnect by stopping port urbs at
port_remove.

Since commit 0998d06310 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer accessible at
disconnect or release.

Note that this patch also fixes port and interface-data memory leaks in
the error path of attach should port initialisation fail for any port.

Compile-only tested.

Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)
Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
stuff.
Tip 'o the hat to IBM (and previously Linuxcare :) for supporting
staff in their work on open source projects.
See keyspan.c for update history.
