[Lapack] Minor bug in DTRSYL

And vsima@Domain.Removed writes:
I would like to draw your attention to a very minor bug in the file
dtrsyl.f (version 3.2, November 2006).  Specifically, the line 167,
SCALE = ONE
must be moved before the line 152 (Section "Quick return if possible"),
since this should be an output even if min(M,N) = 0.

Committed that fix, thanks!

I doubt if LAPACK is completely consistent with zero-dimension matrices,
though.  Any other such fixes happily accepted!
