[PATCH 5/7] packed-ring: fix plurals

There are two instances where plural needs to be used instead of
singular:

1. "descriptor(s)" is used later in the text, so use it consistently
   instead of starting with "descriptor" and switching later.

2. "What follows is the requirements" ->
   "What follows are the requirements"
