Make the cipher/decipher/hash/hmac update() methods ignore the input encoding when the input is a buffer. This is the documented behavior but some inputs were rejected, notably when the specified encoding is 'hex' and the buffer has an odd length (because a _string_ with an odd length is never a valid hex string.) The sign/verify update() methods work okay because they use different validation logic. Fixes: nodejs#31751
