i2c: i2c-msm-geni: Handle NACK interrupt as an error condition

This change adds the NACK bit into the error condition check. So far
driver was expecting for the M_CMD_FAILURE bit also to be raised by
GENI whenever NACK comes, but it's observed that some cases we have
first NACK and then immediately  M_CMD_FAILURE.

This patch helps i2c client to detect NACK as an error and then can
proceed with CMD_FAILURE/CMD_SUCCESS as raised by HW.
