Authored by David S. Miller

Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

isdn: hfc_usb: Fix set-but-unused variables. 

The variable 'buf' is set but unused in
ctrl_complete().  Just kill it off.

Similarly for 'err' in hfc_usb_init().
