passwd: initialize pointers correctly
Fix for running passwd as root (or sudo passwd $USER). Crashed on call to free(orig) during cleanup. Fix regression from commit 17058a06c4333fc0c492c168c8a971ebd0fd5a5a Root user never changes the orig pointer, so when cleaning up, passwd tried to free orig=(char*)"" Example: sudo passwd $USER Changing password for xxx New password: Bad password: too short Retype password: Passwords don't match free(): invalid pointer Aborted function old new delta passwd_main 958 961 +3 Signed-off-by: Einar Jón <tolvupostur@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
