HID: ft260: fix a NULL pointer dereference in ft260_i2c_write
The zero-length passed into the ft260_i2c_write() triggered the
NULL pointer dereference in the debug message on data[0] access.
Since the controller does not support a write of zero length,
let's not allow it.
Before:
$ sudo i2ctransfer -y 13 w0@0x51
Killed
After:
$ sudo i2ctransfer -y 13 w0@0x51
