[Lapack] *GEQRT immediate return



The *GEQRT routines are supposed to return immediately when
n=0 or m=0.
However the code is such that an INFO = -3 is triggered since
we are trying to satisfy
          NB>=1 .and. NB<=MIN(M,N) = 0

Should be

If (NB<1 .or. (NB>Min(M,N) .and. Min(M,N)>0) Then
     INFO = -3
