net: sock_diag: Fix spectre v1 gadget in __sock_diag_cmd()
[ Upstream commit 66b51b0a0341fd42ce657739bdae0561b0410a85 ]
req->sdiag_family is a user-controlled value that's used as an array
index. Sanitize it after the bounds check to avoid speculative
out-of-bounds array access.
This also protects the sock_is_registered() call, so this removes the
sanitize call there.
Fixes: e978de7a6d38 ("net: socket: Fix potential spectre v1 gadget in sock_is_registered")
