sae: fix inproper return value in sae_verify_accepted

Browse Source 
This function was returning a boolean and the expected return was
a signed integer. Since this function actually returned false in
all cases the check for a success (0) return always worked.

The comment about the 'standard code path' was removed as this is
no longer valid.
