docs/sp_SP: Remove ZERO WIDTH SPACE in memory-barriers.txt

As this file is included literally, ZERO WIDTH SPACE causes
"make pdfdocs" to emit messages which read:

  Missing character: There is no ​ (U+200B) in font DejaVu Sans Mono/OT:script=latn;language=dflt;!
  Missing character: There is no ​ (U+200B) in font DejaVu Sans Mono/OT:script=latn;language=dflt;!

U+200B (ZERO WIDTH SPADE) has no effect in literal blocks.
Remove them and get rid of those noises.
