Mikhail Lobanov 959974bf5d drbd: Add NULL check for net_conf to prevent dereference in state validation 
commit a5e61b50c9f44c5edb6e134ede6fee8806ffafa9 upstream.

If the net_conf pointer is NULL and the code attempts to access its
fields without a check, it will lead to a null pointer dereference.
Add a NULL check before dereferencing the pointer.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 44ed167da7 ("drbd: rcu_read_lock() and rcu_dereference() for tconn->net_conf")
