nsswitch: fix crash on null pam change pw response

The function _pam_winbind_change_pwd crashes due to a null value passed
to the function strcasecmp and denies to login via graphical login
manager. Check for a null value before doing a strcasecmp.

(Desktop Managers (xdm, gdm, lightdm...) crashes with SIGSEGV in
_pam_winbind_change_pwd() when password is expiring)
