can: usb: PCAN-USB Pro: fix mem leaks in pcan_usb_pro_init() on error paths

If either call to pcan_usb_pro_send_req() in
drivers/net/can/usb/peak_usb/pcan_usb_pro.c::pcan_usb_pro_init()
fails, we'll leak the memory we allocated to 'usb_if' with kzalloc()
when the 'usb_if' variable goes out of scope without having been
assigned to anything as we 'return err;'.
Fix this by adding appropriate kfree(usb_if) calls to the error paths.
