[PATCH] scsi: iscsi_tcp: Explicitly cast param in iscsi_sw_tcp_host_get_param

[Nathan Chancellor]

Clang warns when one enumerated type is implicitly converted to another.

drivers/scsi/iscsi_tcp.c:803:15: warning: implicit conversion from
enumeration type 'enum iscsi_host_param' to different enumeration type
'enum iscsi_param' [-Wenum-conversion]
                                                 &addr, param, buf);
                                                        ^~~~~
1 warning generated.

iscsi_conn_get_addr_param handles ISCSI_HOST_PARAM_IPADDRESS just fine
so add an explicit cast to iscsi_param to make it clear to Clang that
this is expected behavior.
