sat_vapor_pres does not output location of bad temperatures (unless it's on a root pe)

[wfcooke]

If I set
show_all_bad_values = true
in sat_vapor_pres_nml I expect to see reports of locations of bad temperatures in my stdout. I do not.

The issue is that the output line
e.g.

FMS/sat_vapor_pres/include/sat_vapor_pres.inc

Line 1919 in 2b05550

write(iunit,'(a,e10.3,a,i4,a,i6)') 'Bad temperature=',temp(i),' at i=',i,' pe=',mpp_pe()

uses stdout as the output unit.
stdout is only defined for root pe

If I use stderr instead at

FMS/sat_vapor_pres/sat_vapor_pres.F90

Line 816 in 2b05550

stdoutunit = stdout()

I get the output I need.
For readability stdoutunit should probably be changed to stderrunit (and set to stderr) in the sat_vapor_pres codeset.
