Log message:
moduser: fix use-after-free when locking/unlocking an account.
The pw_tmp and shell_tmp variables are used to store updated versions
of pwp->pw_passwd and pwp->pw_shell when locking and unlocking an
account. The syslog() calls at the end of the function may use
pwp->pw_shell (which can point to shell_tmp) so we must wait until
after the logging to free the temporary variables.
