docs: vm: zswap.rst: replace some characters 



The conversion tools used during DocBook/LaTeX/html/Markdown->ReST
conversion and some cut-and-pasted text contain some characters that
aren't easily reachable on standard keyboards and/or could cause
troubles when parsed by the documentation build system.

Replace the occurences of the following characters:

	- U+00a0 (' '): NO-BREAK SPACE
	  as it can cause lines being truncated on PDF output

Zswap is a lightweight compressed cache for swap pages. It takes pages that are

in the process of being swapped out and attempts to compress them into a

dynamically allocated RAM-based memory pool.  zswap basically trades CPU cycles

for potentially reduced swap I/O.  This trade-off can also result in a

significant performance improvement if reads from the compressed cache are

faster than reads from a swap device.

* Overcommitted guests that share a common I/O resource can

  dramatically reduce their swap I/O pressure, avoiding heavy handed I/O

  throttling by the hypervisor. This allows more work to get done with less

* Users with SSDs as swap devices can extend the life of the device by

  drastically reducing life-shortening writes.
