[PATCH 06/14] KVM: x86: Move MMIO write tracing into vcpu_mmio_write()

[Sean Christopherson]

Move the invocation of MMIO write tracepoint into vcpu_mmio_write() and
drop its largely-useless wrapper to cull pointless code and to make the
code symmetrical with respect to vcpu_mmio_read().

No functional change intended.
