[OE-core] [PATCH] [RFC]kernel-yocto.bbclass: ensure repatching when HEAD is checked out

In some cases it is seen that kernel_checkout and
validate_branches are run again in simultaneous builds.
During do_patch the kgit-s2q mechanism creates and
checks for the kgit-s2q.last file inside the .git
directory, finds a fence post and starts picking up
patches after that. This can create trouble as
validate_branches checks out the HEAD of the branch
and so the patches should be reapplied rather than
skipped due to finding of the fence post.
