Minor improvements to virtio (allow irqs, allocate page aligned).

Allow irqs to be handled while waiting for virtio reads to complete.

Use native page aligned allocations instead of manually aligning the
data.  This reduces the amount of low memory virtio requires.

Also, some minor white space cleanups.
