Subject: RDMA/core: Increase total number of RDMA ports across all devices
Patch-mainline: v4.20-rc1
Git-commit: 7d65cbf0b0ac7d7eebf397ff9af6645b2b3004c2
References: bsc#1103992 FATE#326009

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.
