[PATCH AUTOSEL 4.9 251/251] IB/iser: Fix dma_nents type definition

From: Max Gurtovoy <maxg@mellanox.com>

[ Upstream commit c1545f1a200f4adc4ef8dd534bf33e2f1aa22c2f ]

The retured value from ib_dma_map_sg saved in dma_nents variable. To avoid
future mismatch between types, define dma_nents as an integer instead of
unsigned.

Fixes: 57b26497fabe ("IB/iser: Pass the correct number of entries for dma mapped SGL")
