This reverts the request chaining implementations of
crypto_acomp_[de]compress() introduced in commit b67a02600372
("crypto: acomp - Add request chaining and virtual addresses") since
request chaining has been removed from acomp subsequently in commit
64929fe8c0a4 ("crypto: acomp - Remove request chaining").

This patch restores the implementations of crypto_acomp_[de]compress()
from prior to commit b67a02600372.

That's not right.  Request chaining has already been removed.
What remains is linear address support which you've just removed
with this patch.
