crypto: fix Hash and Cipher abort on end
Fix Hash and Cipher aborting when using end with hex and specific lengths of chunks. The issue was caused because there was missing validation on the written content from the end method. Note that this actually affects quite a few things in Crypto. This affects decipher/cipher (both deprecated) but also decipheriv/cipheriv as well as Hash and Hmac.
I wasn't sure if this should throw in _transform or create an error and provide it to the callback, but according to the stream docs providing an error to the callback is what's expected - so I would love to get some input on my fix, and if it makes sense.
