Issue Description

Generated kernel.cpp code from vitis simulation has a missing argument to the buffer functions that looks like the following:

host.cpp: In function ‘int main(int, char**)’:
host.cpp:107:99: error: expected primary-expression before ‘.’ token

The error can be reproduced by running the pipelined version of Sobel example addressed in PR #384 .

It turns out to be a one line change of code for the fix. Will push the fix in a separate PR.
