Fix possible invalid free in irecv_open_with_ecid()
irecv_open_with_ecid calls libusb_open() in a loop. When the operation
fails libusb_close() is called with the returned handle - which ideally
should be NULL upon calling libusb_open(). However since we're operating
in a loop this is only the case for the first time libusb_open() is called
and subsequent invocations only overwrite the handle upon success.
Whenever the libusb_open() fails and it is not the first invocation, the
libusb_close() that is called afterwards may cause an invalid free.
To prevent this we set the handle to NULL before calling libusb_open().
