    nvmm: Revert to use os_curcpu() in vmx_vmcs_enter()
    
    os_curcpu() returns a pointer to the current per-cpu data, which is used
    in vmx_vmcs_enter() to clear a VMCS from a remote CPU.  So it's more
    efficient and clean than using the os_curcpu_number(), which requires
    another lookup to obtain the per-cpu data pointer from the CPU id.
    
    This effectively reverts the commit:
    nvmm: Fix issues of porting 'curcpu()' as 'mycpu'
    
    The "VMX fail valid" panics I had then were actually caused by the
    missing wait for the asynchronous IPI request to clear VMCS from a
    remote CPU, which had been fixed in a later commit.
