revert "net: kcm: fix memory leak in kcm_sendmsg"

Browse Source 
In commit c47cc30499 ("net: kcm: fix memory leak in kcm_sendmsg")
I misunderstood the root case of the memory leak and came up with
completely broken fix.

So, simply revert this commit to avoid GPF reported by
syzbot.

Im so sorry for this situation.
