First off, these function do lock sysctl exclusively, so I find this to
be a better suited name.

In https://svnweb.freebsd.org/base?view=revision&revision=273401 I added
shared locking to sysctl and this change "coincidently" freed up a nice
name for a functions which remember previous lock type and lock it the
same way later.
