The 'identparams' typed parameter list obtained from
virIdentityGetParameters is leaked when called from
'virGetConnectGeneric'.
Use 'virTypedParamListFromParams' to absorb it into a virTypedParamList
which can be autofreed.
Note that the memleak is observable only when running in split-daemon
mode.
