[OE-core] [PATCH] Revert "kernel.bbclass: adjust a condition checking"

[Jason Wessel]

This reverts commit 6676411fccff2d331878e4ca1f9411aafb056a80.

This revert restores the original code and adds a comment.  The commit
that was reverted broke a number of wic templates and tools which rely
on the initramfs creation dependency and the case where the
INITRAMFS_IMAGE_BUNDLE is not set.

If an end user does not want the INITRAMFS_IMAGE generated, it should
be set to "".
