Many users of kernel async. crypto services have a pattern of starting an async. crypto op and than using a completion to wait for it to end, resulting of the same code repeating itself in multiple places, sometime with coding errors. This patch aims to introduce a generic "wait for async. crypto op to complete" functions and move all the users I could find to use it. This gets rid of almost 300 lines of code and uncovered a few bugs in existing code (separate bug fix patch set sent previously). The patch set was boot tested on x86_64 and arm64 which at the very least tests the crypto users via testmgr but I am less confident regarding some of the other users and would love more testers. Changes from v1: - Address review comments from Eric Biggers. - Separated out bug fixes of existing code and rebase on top of that patch set. - Rename 'ecr' to 'wait' in fscrypto code. - Split patch introducing the new API from the change moving over the algif code which it originated from to the new API. - Inline crypto_wait_req(). - Some code indentation fixes.
