Remove set but unused variables in usr/src/cmd
GCC-4.9.4, and probably later versions, identifies variables that are set but not otherwise used in source files, with an error message like this one:
uuglist.c: In function 'rproc': uuglist.c:132:6: error: variable 'na' set but not used [-Werror=unused-but-set-variable] int na; ^ cc1: all warnings being treated as errors
In a large number of cases, simply removing the offending variable will prevent this error, and permit the file to be compiled. In more complex cases, other means have to be considered instead.
