dann frazier 9d39058523 kernel_lockdown.7: Remove additional text alluding to lifting via SysRq 
My previous patch intended to drop the docs for the lockdown lift
SysRq, but it missed this other section that refers to lifting it
via a keyboard - an allusion to that same SysRq.

dann frazier a989677777 kernel_lockdown.7: Remove description of lifting via SysRq (not upstream) 
The patch that implemented lockdown lifting via SysRq ended up
getting dropped[*] before the feature was merged upstream. Having
the feature documented but unsupported has caused some confusion
for our users.
