From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
commit 97f53a08cba128a724ebbbf34778d3553d559816 upstream.
The previous Kconfig patch led to some other build errors as
reported by the 0day bot and my own overnight build testing.
These are all in <linux/skbuff.h> when KCOV is enabled but
SKB_EXTENSIONS is not enabled, so fix those by combining those conditions
in the header file.
Fixes: 6370cc3bbd8a ("net: add kcov handle to skb extensions")
Fixes: 85ce50d337d1 ("net: kcov: don't select SKB_EXTENSIONS when there is no NET")
