usb: usbtmc: Fix erroneous generic_read ioctl return
commit 4e77d3ec7c7c0d9535ccf1138827cb9bb5480b9b upstream.
wait_event_interruptible_timeout returns a long

when the remaining jiffies > INT_MAX which resulted in random error
returns.
Use a long return value, converting to the int ioctl return only on error.
