Revert "Pre-allocate vdev I/O buffers"
Commit 86dd0fd added preallocated I/O buffers. This is no longer
required after the recent kmem changes designed to make our memory
allocation interfaces behave more like those found on Illumos. A
deadlock in this situation is no longer possible.
However, these allocations still have the potential to be expensive.
So a potential future optimization might be to perform then KM_NOSLEEP
so that they either succeed of fail quicky. Either case is acceptable
here because we can safely abort the aggregation.
