i2c-dev: Reject I2C_M_RECV_LEN
The I2C_M_RECV_LEN calling convention for i2c_mesg.flags involves playing games with reported buffer lengths. (They start out less than their actual size, and the length is then modified to reflect how many bytes were delivered ... which one hopes is less than the presumed actual size.) Refuse to play such error prone games across the boundary between userspace and kernel.
