Pankaj Raghav 14e75ed721 disk_benchmark: Remove the call to umask ...

Calling umask and open with same permission value will result in a file
with no permissions bits if the program is stopped while it is doing an
IO. This will result in an error with EACCES when we try to run the
benchmark with the same file name. The file needs to be manually
removed before continuing the benchmark.

There is no use in calling umask here, so just remove it so that
interrupting the program while it is doing an IO will not result int the
file with no permissions the next time we run the program.
