   ## Summary
   Allow zero-length I2C transfers when DEBUGASSERT is enabled.
   
   Zero-length transfers (used for I2C bus scanning) never access the transfer 
buffer, so any EasyDMA pointer is valid.
   
   `i2c dev -z` command is still broken for nordic chips, but at least it 
doesn't crash.
   
   ## Impact
   bugfix
   
   ## Testing
   I2C bus scan on Nordic Power Kit 2
