Eugen Hristev 73c16692bc i2c: at91: fix crash when using 'i2c probe' 
When issuing 'i2c probe', the driver was crashing, because at probe
there is a request with zero length buffer to write to i2c bus.
The xfer_msg function assumes the buffer is always there, and never
checks for the buffer length.

=> i2c dev 0
Setting bus to 0
=> i2c probe
