Of course crypto_wait_req cannot return -EINPROGRESS.  However,
I was responding to a request to make the crypto_acomp_compress
call return a boolean instead of an error code.  That is not
possible because it has to be able to return -EINPROGRESS.

Nor is it possible to change crypto_wait_req to be boolean since
other Crypto API operations (including decompression) can indeed
fail.
