af851914f810978909dd8598ab88030fe43d0051 ('Make
tls_connection_get_keyblock_size() internal to tls_*.c') broke
tls_connection_prf() with the internal TLS implementation when using
skip_keyblock=1. In practice, this broke EAP-FAST. Fix this by deriving
the correct number of PRF bytes before skipping the keyblock.
