Subject: [PATCH] setup.sh: redirect modprobe msr error messages to /dev/null

We try to modprobe msr so that DPDK can more easily figure
out TSC on x86 systems.  But that just results in a
"Module msr not found" message on non-x86 systems.  setup.sh
still works, but the error message makes it appear
otherwise.  So just redirect the error message to reduce
this confusion.
