    Fix pem_passwd_cb(): unused variable "rwflag" (OpenSSL)

    This patch fixes the following warning of GCC (version 4.3.2) in
    function pem_passwd_cb() when compiling with OpenSSL support and
    without debug code:

    conn-ssl.c: In function 'pem_passwd_cb':
    conn-ssl.c:122: warning: unused parameter 'rwflag'
