Sumit Garg 13e83186c9 kgdb: fix to kill breakpoints on initmem after boot 
commit d54ce6158e upstream.

Currently breakpoints in kernel .init.text section are not handled
correctly while allowing to remove them even after corresponding pages
have been freed.

Fix it via killing .init.text section breakpoints just prior to initmem
pages being freed.

Doug: "HW breakpoints aren't handled by this patch but it's probably
not such a big deal".
