ntb: intel: fix return value for ndev_vec_mask()

Browse source 
[ Upstream commit 7756e2b5d68c36e170a111dceea22f7365f83256 ]

ndev_vec_mask() should be returning u64 mask value instead of int.
Otherwise the mask value returned can be incorrect for larger
vectors.

Fixes: e26a5843f7 ("NTB: Split ntb_hw_intel and ntb_transport drivers")
