Ignat Korchagin 79e16a0d33 net: inet6: do not leave a dangling sk pointer in inet6_create() ...

[ Upstream commit 9df99c395d0f55fb444ef39f4d6f194ca437d884 ]

sock_init_data() attaches the allocated sk pointer to the provided sock
object. If inet6_create() fails later, the sk object is released, but the
sock object retains the dangling sk pointer, which may cause use-after-free
later.

Clear the sock sk pointer on error.
