[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.
