[PATCH 3/8] saa7114: Fix i2c block write

[Jean Delvare <khali@linux-fr.org>]

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.
