Liming Sun 61c3962ab1 platform/mellanox: fix potential race in mlxbf-tmfifo driver
[ Upstream commit 3d43f9f639 ]

This commit adds memory barrier for the 'vq' update in function
mlxbf_tmfifo_virtio_find_vqs() to avoid potential race due to
out-of-order memory write. It also adds barrier for the 'is_ready'
flag to make sure the initializations are visible before this flag
is checked.
