Add support of NOIO allocations to IPoIB

From: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/[email protected]>

Hi Doug,

These patches adds native support to NOIO allocations during create QP for IPoIB.

In contrast to the commit 09b93088d750 ("IB: Add a QP creation flag to use GFP_NOIO allocations"), which added specific QP create flag, this series uses standard memalloc_noio_* calls to mark GFP_NOIO for all allocations paths below.

This change allows to all drivers benefit from this facitlity and not only mlx4 and qib. As a nice outcome, there is a lot simplification in the mlx4 and qib drivers by removing need to carry GFP flags.

Thanks
