[ Upstream commit a861594b1b7ffd630f335b351c4e9f938feadb8e ]
The tx_time should be in usecs (according to the comment above the
variable), but the setting of the timer during the rearming is done in
msecs. Change it to match the expected units.
Fixes: e74bfeedad08 ("NTB: Add flow control to the ntb_netdev")

[ 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.
