RDMA/core: Increase total number of RDMA ports across all devices
IDA adds overhead to store IDs bitmap with maximal value of IDA can be upto 2099202 (IDA_MAX = 0x80000000U / IDA_BITMAP_BITS - 1). However, there is no need to add such enormous number of devices and it is enough for now to limit it to be 8192.
