V4L/DVB (3568a): saa7114: Fix i2c block write
Fix the i2c block write mode of the saa7114 driver. A previous code change accidentally commented out a local variable increment, which should have been kept, causing the register writes over the I2C bus to never be batched, replacing any attempted block write by slower, individual write transactions. Also drop the commented out code, as it only adds to confusion.
