[PATCH] net/llc/llc_conn.c: fix 4 instances of -Wmissing-variable-declarations

[Nick Desaulniers <ndesaulniers@google.com>]

I'm looking to enable -Wmissing-variable-declarations behind W=1. 0day
bot spotted the following instances:

  net/llc/llc_conn.c:44:5: warning: no previous extern declaration for
  non-static variable 'sysctl_llc2_ack_timeout'
  [-Wmissing-variable-declarations]
  44 | int sysctl_llc2_ack_timeout = LLC2_ACK_TIME * HZ;
     |     ^
  net/llc/llc_conn.c:44:1: note: declare 'static' if the variable is not
  intended to be used outside of this translation unit

     |     ^
  net/llc/llc_conn.c:46:1: note: declare 'static' if the variable is not

  net/llc/llc_conn.c:47:5: warning: no previous extern declaration for
  non-static variable 'sysctl_llc2_busy_timeout'
  [-Wmissing-variable-declarations]
  47 | int sysctl_llc2_busy_timeout = LLC2_BUSY_TIME * HZ;
     |     ^
  net/llc/llc_conn.c:47:1: note: declare 'static' if the variable is not

     | ^

These symbols are referenced by more than one translation unit, so make
include the correct header for their declarations. Finally, sort the
list of includes to help keep them tidy.
