KVM: nVMX: Remove a rogue "rax" clobber from nested_vmx_check_vmentry_hw()
commit 9ce0a07a6f49822238fd4357c02e0dba060a43cc upstream.
RAX is not touched by nested_vmx_check_vmentry_hw(), directly or
indirectly (e.g. vmx_vmenter()). Remove it from the clobber list.
Fixes: 52017608da33 ("KVM: nVMX: add option to perform early consistency checks via H/W")
