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'
