investivating #817:
* Remove use of legal_numbits member and always just use the full
size of the array. There was a corner case where legal_numbits was
not an even multiple of the number of bits in the array where bits
would not get freed properly, ususally causing wasted fortran
MPI handles, or, as in the case of #817, wasted attribute keyvals
(i.e., the user freed them, but the bitmap didn't reflect the
free).
* Re-order some error checks to ensure that we don't segv (we don't
currently trigger this problem anywhere; I just noticed it while
doing the other attribute keyval and legal_numbits work).
Since this change affects all Fortran MPI handles, I ran all the intel
and ibm tests and all still pass with this change.
