[PATCH] kernel_lockdown.7: Remove description of lifting via SysRq (not upstream)

[PATCH] kernel_lockdown.7: Remove description of lifting via SysRq (not upstream)

[dann frazier]

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.
