Brooks Davis bed230409f SSIDs are of length 32-bytes and not NUL terminated. Use the correct 
length and bail immediatly if the returned length is wrong rather than
attempting to set an correct value.

This commit differs from the patch in the PR in the use of exit instead
of return and the use of a defined value for the array.
