[DCCP]: Remove duplicate test for CloseReq
This removes a redundant test for unexpected packet types. In dccp_rcv_state_process
it is tested twice whether a DCCP-server has received a CloseReq (Step 7):
* first in the combined if-statement,
* then in the call to dccp_rcv_closereq().
The latter is necesssary since dccp_rcv_closereq() is also called from
__dccp_rcv_established().
This patch removes the duplicate test.
