Subject: [PATCH v4 02/12] Revert "kgdboc: disable the console lock when in kgdb"

This reverts commit 81eaadcae81b4c1bf01649a3053d1f54e2d81cf1.

Commit 81eaadcae81b ("kgdboc: disable the console lock when in kgdb")
is no longer needed now that we have the patch ("kgdb: Disable
WARN_CONSOLE_UNLOCKED for all kgdb").  Revert it.
