[PATCH v2 0/4] crypto: async crypto op fixes

[Gilad Ben-Yossef]

This patch set fixes various usage and documentation errors
in waiting for async crypto op to complete which can result
in data corruption.

Note: these were discovered in the process of working on a
patch set that replaces these call sites and more with a
generic implementation that will prevent these problems
going forward. These are just the fix ups for current code.
