IB/uverbs: Set IOVA on IB MR in uverbs layer
[ Upstream commit 04c0a5fcfcf65aade2fb238b6336445f1a99b646 ]
Set IOVA on IB MR in uverbs layer to let all drivers have it, this
includes both reg/rereg MR flows.
As part of this change cleaned-up this setting from the drivers that
already did it by themselves in their user flows.
Fixes: e6f0330106f4 ("mlx4_ib: set user mr attributes in struct ib_mr")
