Revert "BACKPORT, FROMLIST: fscrypt: add Speck128/256 support"

This reverts commit 4b08356a76b859b8f4599bf8821a6702ac50a029.

Resolves conflicts with a later CL, e7724207f71e "fscrypt: log the
crypto algorithm implementations".

[astrachan: This is an update to 076c36fce1ea which reverted only
            the fscrypt changes, not the ext4 changes, due to a
            historical bad merge.]
