include/rdma/opa_addr.h: Fix an endianness issue
IB_MULTICAST_LID_BASE is defined as follows:
#define IB_MULTICAST_LID_BASE cpu_to_be16(0xC000)
Hence use be16_to_cpu() to convert it to CPU endianness. Compile-tested
only.
Fixes: af808ece5ce9 ("IB/SA: Check dlid before SA agent queries for ClassPortInfo")
