Bug description:
  Guest kernel panic for VMs in enhanced session mode when the XRDP
  channel connection happens too early in the boot.

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=c1eef220c1760762753b602c382127bfccee226d

  vsock: always call vsock_init_tables()
  Although CONFIG_VSOCKETS_DIAG depends on CONFIG_VSOCKETS,
  vsock_init_tables() is not always called, it is called only
  if other modules call its caller. Therefore if we only
  enable CONFIG_VSOCKETS_DIAG, it would crash kernel on uninitialized
  vsock_bind_table.

  This patch fixes it by moving vsock_init_tables() to its own
  module_init().
