[bufferorch] Handle NOT IMPLEMENTED status returned during set attr operation (sonic-net#1639)

Set operations for some attributes of buffer pool and buffer profile may not be implemented by some vendors and they return SAI_STATUS_ATTR_NOT_IMPLEMENTED_0. Handle that status in the code and ignore that task
