inode->i_ino is being converted to a u64. sock.sk_ino (which caches the
inode number) must also be widened to avoid truncation on 32-bit
architectures where unsigned long is only 32 bits.

Change sk_ino from unsigned long to u64, and update the return type
of sock_i_ino() to match. Fix all format strings that print the
result of sock_i_ino() (%lu -> %llu), and widen the intermediate
variables and function parameters in the diag modules that were
using int to hold the inode number.

Note that the UAPI socket diag structures (inet_diag_msg.idiag_inode,
unix_diag_msg.udiag_ino, etc.) are all __u32 and cannot be changed
without breaking the ABI. The assignments to those fields will
silently truncate, which is the existing behavior.
