Steven Rostedt (VMware) 1503538843 x86/cpu/vmware: Do not trace vmware_sched_clock()
When running function tracing on a Linux guest running on VMware
Workstation, the guest would crash. This is due to tracing of the
sched_clock internal call of the VMware vmware_sched_clock(), which
causes an infinite recursion within the tracing code (clock calls must
not be traced).

Make vmware_sched_clock() not traced by ftrace.

Fixes: 80e9a4f21f ("x86/vmware: Add paravirt sched clock")
