Subject: RDMA/rxe: Save a few bytes from struct rxe_pool
Patch-mainline: v5.16-rc1
Git-commit: 69d1ed59999c1e9c823f78befd3fb8a22bdbff48
References: jsc#SLE-19249

'table_size' is never read, it can be removed.

In fact, the only place that uses something that could be 'table_size' is
'alloc_index()'. In this function, it is re-computed from 'min_index' and
'max_index'.
