Summary
isdn: mISDN: hfcsusb: fix memory leak in hfcsusb_probe()
Details

In the Linux kernel, the following vulnerability has been resolved:

isdn: mISDN: hfcsusb: fix memory leak in hfcsusb_probe()

In hfcsusbprobe(), the memory allocated for ctrlurb gets leaked when setup_instance() fails with an error code. Fix that by freeing the urb before freeing the hw structure. Also change the error paths to use the goto ladder style.

Compile tested only. Issue found using a prototype static analysis tool.
