RDMA/efa: Fix unsupported page sizes in device

[ Upstream commit 866422cd ]

Device uses 4KB size blocks for user pages indirect list while the
driver creates those blocks with the size of PAGE_SIZE of the kernel. On
kernels with PAGE_SIZE different than 4KB (ARM RHEL), this leads to a
failure on register MR with indirect list because of the miss
communication between driver and device.
