[PATCH 02/22] iio: adc: ti-ads7138: Remove redundant i2c_master_send() length checks

[Jonathan Cameron <jonathan.cameron@oss.qualcomm.com>]

i2c_master_send() returns either a negative errno or exactly the count
passed in, so a length check after the 'ret < 0' test can never be true.
Drop the dead branches.
