ssl: Fix encoding/decoding of the SRP extension
The encoded value of the SRP extension length was bigger than the actual length of the extension. This could cause interoperability problems with third party SSL implementations. This commit corrects the encoding and decoding of the SRP extension length. Change-Id: I78d118faab7f5d02b755a7d1e2e8561b86f5a15c
