ib_srpt: Destroy cm_id before destroying QP.
This patch fixes a bug where ib_destroy_cm_id() was incorrectly being called after srpt_destroy_ch_ib() had destroyed the active QP. This would result in the following failed SRP_LOGIN_REQ messages: Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff1762bd, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 1 (guid=0xfe80000000000000:0x2c903009f8f41) Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff1758f9, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 2 (guid=0xfe80000000000000:0x2c903009f8f42) Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff175941, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 2 (guid=0xfe80000000000000:0x2c90300a3cfb2) Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff176299, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 1 (guid=0xfe80000000000000:0x2c90300a3cfb1) mlx4_core 0000:84:00.0: command 0x19 failed: fw status = 0x9 rejected SRP_LOGIN_REQ because creating a new RDMA channel failed.
