docs: kvm: fix referenced ioctl symbol
The actual symbol that is exported and usable is
'KVM_MEMORY_ENCRYPT_OP', not 'KVM_MEM_ENCRYPT_OP'
$ git grep -l KVM_MEM_ENCRYPT_OP
Documentation/virt/kvm/amd-memory-encryption.rst
$ git grep -l KVM_MEMORY_ENCRYPT_OP
Documentation/virt/kvm/api.rst
arch/x86/kvm/x86.c
include/uapi/linux/kvm.h
tools/include/uapi/linux/kvm.h
While we're in there, update the KVM API category for
KVM_MEMORY_ENCRYPT_OP. It is called on a VM file descriptor.
