SUNRPC: Add a missing spin_unlock to gss_mech_list_pseudoflavors
The patch "SUNRPC: Add rpcauth_list_flavors()" introduces a new error path in gss_mech_list_pseudoflavors, but fails to release the spin lock. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
