debug_core,kdb: fix kgdb_connected bit set in the wrong place



Immediately following an exit from the kdb shell the kgdb_connected
variable should be set to zero, unless there are breakpoints planted.
If the kgdb_connected variable is not zeroed out with kdb, it is
impossible to turn off kdb.

This patch is merely a work around for now, the real fix will check
for the breakpoints.
