usb: host: fhci-sched: Remove unused variable 'td'

'td' has been completely unused since the driver's inception in 2009.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/host/fhci-sched.c: In function ‘fhci_queue_urb’:
 drivers/usb/host/fhci-sched.c:704:13: warning: variable ‘td’ set but not used [-Wunused-but-set-variable]
 704 | struct td *td;
 | ^~
