[PATCH v2 net-next 1/1] plca.c: fix obvious mistake in checking retval

[Piergiorgio Beruto]

This patch addresses a wrong fix that was done during the review
process. The intention was to substitute "if(ret < 0)" with
"if(ret)". Unfortunately, in this specific file the intended fix did not
meet the code. After additional review, it seems like if(ret < 0) was
actually the right thing to do. So this patch reverts those changes.

Try to reword the patch description without writing "This patch does foo"
(prefer imperative mood over descriptive one).

Thanks.
