IB/rxe: Remove unnecessary enum values
Clang warns when an emumerated type is implicitly converted to another. drivers/infiniband/sw/rxe/rxe.c:106:27: warning: implicit conversion from enumeration type 'enum rxe_device_param' to different enumeration type 'enum ib_atomic_cap' [-Wenum-conversion] rxe->attr.atomic_cap = RXE_ATOMIC_CAP; ~ ^~~~~~~~~~~~~~ drivers/infiniband/sw/rxe/rxe.c:131:22: warning: implicit conversion from enumeration type 'enum rxe_port_param' to different enumeration type 'enum ib_port_state' [-Wenum-conversion] port->attr.state = RXE_PORT_STATE; ~ ^~~~~~~~~~~~~~ drivers/infiniband/sw/rxe/rxe.c:132:24: warning: implicit conversion from enumeration type 'enum rxe_port_param' to different enumeration type 'enum ib_mtu' [-Wenum-conversion] port->attr.max_mtu = RXE_PORT_MAX_MTU; ~ ^~~~~~~~~~~~~~~~ drivers/infiniband/sw/rxe/rxe.c:133:27: warning: implicit conversion from enumeration type 'enum rxe_port_param' to different enumeration type 'enum ib_mtu' [-Wenum-conversion] port->attr.active_mtu = RXE_PORT_ACTIVE_MTU; ~ ^~~~~~~~~~~~~~~~~~~ drivers/infiniband/sw/rxe/rxe.c:151:24: warning: implicit conversion from enumeration type 'enum rxe_port_param' to different enumeration type 'enum ib_mtu' [-Wenum-conversion] ib_mtu_enum_to_int(RXE_PORT_ACTIVE_MTU); ~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~~~~~ 5 warnings generated. Use the appropriate values from the expected enumerated type so no conversion needs to happen then remove the unneeded definitions.
