vt,console,kdb: preserve console_blanked while in kdb

Commit b45cfba4e9005d64d419718e7ff7f7cab44c1994 (vt,console,kdb:
implement atomic console enter/leave functions) introduced the ability
to atomically change the console mode with kernel mode setting but did
not preserve the state of the console_blanked variable.

The console_blanked variable must be restored when executing the
con_debug_leave() or further kernel mode set changes (such as using
chvt X) will fail to correctly set the state of console.
