  -----------
  raster: Fix three single-alert CodeQL findings (#7702)

r.watershed(ram): checking sscanf against 0 misses the EOF return, so
use != 1 as the seg variant already does. 
r.viewshed: bound the inner
column loop by the local int ncols cast to dimensionType, matching the
row loop, instead of comparing the unsigned short counter directly to
Rast_window_cols().
r.in.gdal: drop the null check on sdsdesc, which
is always assigned a non-null pointer beforehand.
