Commit ffbd0c8c ("wifi: mac80211: add an element parsing unit test")
and commit 730eeb17 ("wifi: cfg80211: add first kunit tests, for
element defrag") add new configs that depend on !KERNEL_6_2, but the config
option KERNEL_6_2 does not exist in the tree. This dependency is used for
handling backporting to restrict the option to certain kernels but this
really should not be carried around the mainline kernel tree.

Clean up this needless dependency on the non-existing option KERNEL_6_2.
