Subject: RDMA/ocrdma: Fix structure layout for ocrdma_alloc_pd
Patch-mainline: v4.17-rc1
Git-commit: f64705b8715a090cd5526a2c082eeb199a51e8b2
References: bsc#1103992 FATE#326009

The udata's for alloc_pd cannot contain u64s due to alignment
constraints. Switch the two never-used u64's to arrays of u32 to reduce
the required struct alignment to 4 bytes.

These reserved fields are totally unnecessary, never written and never
read.
