Fix bug bug0088 reported by Mike Pont from NAG on the forum
(see http://icl.cs.utk.edu/lapack-forum/viewtopic.php?f=13&t=2893)

Actually there were a lot of problems regarding arguments checking.
I tried to correct most of them.

Apply the fix propose to all x[he/sy]rfsx.f routines
- Use IGNORE_CWISE as suggested to prevent use of unitialize variable PARAMS

I also appied the previous TESTING fix to all routines

INFO has new value in ZHERFSX (see description of INFO between ZHESVX and ZHESVXX)
This is set on line 634 (IF ( INFO .LE. N ) INFO = N + J) of zherfsx.f
And this is not handled by the testing LIN/zdrvhex.f
I just add  .AND. INFO.LE.N at line 638 to avoid raising an error when INFO = N + J

At the moment, I would recommand a further look at those routines.
ZHE, ZSY led to 182 Tests failing to pass the threshold
and the same for complex

better than before, but still....
