i2cdump: use I2C block mode for the 'i' mode parameter

Currently we're calling i2c_smbus_read_block_data() for both 'i' and 's'
mode parameters. If the bus doesn't support SMBus block mode, then the
i2c access ioctl() fails. Make i2cdump behave compatibly with upstream
version by calling i2c_smbus_read_i2c_block_data() for I2C block.
