llc: Constify struct llc_conn_state_trans

'struct llc_conn_state_trans' are not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
13923 10896 32 24851 6113 net/llc/llc_c_st.o

After:
