Ignat Korchagin 25447c6aaa net: inet: do not leave a dangling sk pointer in inet_create() 
[ Upstream commit 9365fa510c ]

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

Clear the sk pointer in the sock object on error.
