usb: return correct errno on failures
In function __wa_xfer_setup_segs(), variable result takes the return
value. Its value should be a negative errno on failures. Because result
may be reassigned in a loop, and its value is guaranteed to be not less
than 0 during the following repeats of the loop. So when the call to
kmalloc() or usb_alloc_urb() fails in the loop, the value of variable
result may be 0 (indicates no error), which is inconsistent with the
execution status. This patch fixes the bug, initializing variable result
with -ENOMEM in the loop.
