cx23885: Revert "Check for slave nack on all transactions"

commit 67914b5c400d6c213f9e56d7547a2038ab5c06f4 upstream.

This reverts commit 44835f197bf1e3f57464f23dfb239fef06cf89be.

With the CX23885 hardware I2C master, checking for I2C slave ACK/NAK
is not valid when the I2C_EXTEND or I2C_NOSTOP bits are set.
Revert the commit that checks for I2C slave ACK/NAK on all transactions,
so that XC5000 tuners work with the CX23885 again.

Thanks go to Mark Zimmerman for reporting and bisecting this problem.
