mm/gup_benchmark: add a missing "w" to getopt string
Even though gup_benchmark.c has code to handle the -w command-line option, the "w" is not part of the getopt string. It looks as if it has been missing the whole time. On my machine, this leads naturally to the following predictable result: $ sudo ./gup_benchmark -w ./gup_benchmark: invalid option -- 'w' ...which is fixed with this commit.
