drivers: qcom: qmi: Copy the out-of-band data and process it

The address to out-of-band data provided by the underlying data is copied.
The underlying transport frees the address before QMI interface can process
that out-of-band data. This leads to QMI interface accessing stale/invalid
data.

Copy the out-of-band data and process it.
