fscrypt: remove struct fscrypt_ctx
Now that ext4 and f2fs implement their own post-read workflow that supports both fscrypt and fsverity, the fscrypt-only workflow based around struct fscrypt_ctx is no longer used. So remove the unused code. This is based on a patch from Chandan Rajendra's "Consolidate FS read I/O callbacks code" patchset, but rebased onto the latest kernel, folded __fscrypt_decrypt_bio() into fscrypt_decrypt_bio(), cleaned up fscrypt_initialize(), and updated the commit message. Originally-from: Chandan Rajendra <chandan@linux.ibm.com> Signed-off-by: Eric Biggers <ebiggers@google.com>
