Subject: [PATCH RFC V2 2/6] RDMA/rxe: set RXE_PAGE_SIZE_CAP to PAGE_SIZE
RXE_PAGE_SIZE_CAP means the MR page size supported by RXE. However
in current RXE implementation, only PAGE_SIZE MR works well.
So change it to PAGE_SIZE only.
ULPs such as SRP calculating the page size according to this attribute
get worked again with this change.
