qemu: Move qemuDomainSecretPrepare to qemuProcessPrepareDomain

Commit id '40d8e2ba' added the function to qemuProcessStart because
in order to set up some secrets in the future we will need the master
key. However, since the previous patch split the master key creation
into two parts (create just the key and create the file), we can now
call qemuDomainSecretPrepare from qemuProcessPrepareDomain since the
file is not necessary.
