USB: serial: keyspan_pda: remove unused variable

Browse Source 
Remove an unused variable which was mistakingly left by commit
37faf50615 ("USB: serial: keyspan_pda: fix write-wakeup
use-after-free") and only removed by a later change.

This is needed to suppress a W=1 warning about the unused variable in
the stable trees that the build bots triggers.
