usb: usbtmc: Fix bug in pipe direction for control transfers

commit e9b667a8

 upstream.

The syzbot fuzzer reported a minor bug in the usbtmc driver:

usb 5-1: BOGUS control dir, pipe 80001e80 doesn't match bRequestType 0
WARNING: CPU: 0 PID: 3813 at drivers/usb/core/urb.c:412

The problem is that usbtmc_ioctl_request() uses usb_rcvctrlpipe() for
all of its transfers, whether they are in or out.  It's easy to fix.
