KVM: nVMX: Remove a rogue "rax" clobber from nested_vmx_check_vmentry_hw()

Browse Source 
RAX is not touched by nested_vmx_check_vmentry_hw(), directly or
indirectly (e.g. vmx_vmenter()).  Remove it from the clobber list.

Fixes: 52017608da ("KVM: nVMX: add option to perform early consistency checks via H/W")
