Ben Hutchings 20bc319ad3 apparmor: validate default DFA states are in bounds 
Some backports of commit 9063d7e261 ("apparmor: validate DFA start
states are in bounds in unpack_pdb") limited the bounds checks on DFA
start states to the case where the start state was explicit in the
policy.  However, the default DFA start state (DFA_START = 1) could
also be out-of-bounds.

Move these checks out of the else-branches so that they are applied
regardless of how the start state was initialised.
