[PATCH] x86/vmware: Skip timer_irq_works() check on VMware

[Renat Valiullin]

The timer_irq_works() boot check may sometimes fail in a VM, when
the Host is overcommitted or when the Guest is running nested.
Since the intended check is unnecessary on VMware's virtual
hardware, this change by-passes it.
