Documentation: remove nonexistent magic numbers

The entire file blames back to the start of git
(minus whitespace from the RST translation and a typo fix):
  * there are changelog comments for March 1994 through to Linux 2.5.74
  * struct tty_ldisc is two pointers nowadays, so naturally no magic
  * GDA_MAGIC is defined but unused, and it's been this way
    since start-of-git
  * M3_CARD_MAGIC isn't defined, because
    commit d56b9b9c464a ("[PATCH] The scheduled removal of some OSS
    drivers") removed the entire driver in 2006
  * CS_CARD_MAGIC likewise since
    commit b5d425c97f7d ("more scheduled OSS driver removal") in 2007
  * KMALLOC_MAGIC and VMALLOC_MAGIC were removed in
    commit e38e0cfa48ac ("[ALSA] Remove kmalloc wrappers"),
    six months after start of git
  * SLAB_C_MAGIC has never even appeared in git
    (removed in 2.4.0-test3pre6)

magic-number.rst is a low-value historial relic at best and
misleading cruft at worst, so start with cleaning out ones that only
appear therein
