USB: keyspan: fix potential null pointer dereference

Move control-urb dereference to after NULL-check. There is otherwise a
risk of a possible null pointer dereference.

Was largely found by using a static code analysis program called
cppcheck.

[Johan: modify commit message somewhat ]
[gkh: remove stable tag as it's not a real problem that anyone has ever hit]
