Undo SVN rev 183283
Do not use Giant for kbdmux(4) locking. This is wrong and apparently
causing more problems than it solves. This will re-open the issue
where interrupt handlers may race with kbdmux(4) in polling mode.
Typical symptoms include (but not limited to) duplicated and/or
missing characters when low level console functions (such as gets)
are used while interrupts are enabled (for example geli password
prompt, mountroot prompt etc.)
