Avoid unnecessary credentials allocation and initialization by passing the net's cmdline creds to libnetapi_net_init() directly. Fixes the problem of running cli_credentials_guess() (which runs password callbacks) twice, one for the net's cmdline creds and a second time for the creds initialized in libnetapi_net_init(), just to override them immediately after. Example: $ export PASSWD_FD=0 $ ./bin/net offlinejoin composeodj <...> foo bar Password is read from STDIN twice.
