ip6-rewrite: bug fix buffer->error in dual loop
error should be recorded in buffer so that process-error-punt can handle them correctly Per Damjan's comments, move counter to under else clause of last error0==NONE check. Both v4 and v6 are changed. Change-Id: I707c7877ccb12589337155173fc4a5200b42ee93 Signed-off-by: Kingwel Xie <kingwel.xie@ericsson.com>
