[linux-yocto] [PATCH 3/4] kernel-yocto: clarify KMETA branch comments

[Bruce Ashfield]

Having a meta branch is not strictly required by the tools (and
recipes like linux-yocto-custom do not have meta branches), but the
comments in the kernel-yocto.bbclass could lead someone to think that
it was required.

This commit clearifies the comment to the following:

  # We can fix up the kernel repository even if it wasn't a bare clone.
  # If KMETA is defined, the branch must exist, but a machine branch
  # can be missing since it may be created later by the tools.

[YOCTO #3422]
