i2c: robotfuzz-osif: disable zero-length read messages



commit 56ad91c1aa9c18064348edf69308080b03c9dc48 upstream.

This driver passes the length of an i2c_msg directly to
usb_control_msg(). If the message is now a read and of length 0, it
violates the USB protocol and a warning will be printed. Enable the
I2C_AQ_NO_ZERO_LEN_READ quirk for this adapter thus forbidding 0-length
read messages altogether.

Fixes: 83e53a8f ("i2c: Add bus driver for for OSIF USB i2c device.")
