Bug 21431: Add action parameter to set_password

Bug 21431: Add action parameter to set_password

Added to the call in opac-password-recovery.pl. This allows
differentiating between password change and password reset when
viewing the logs.

Test plan:
Enable BorrowersLog.
Do a password recovery on OPAC.
Check with log viewer for 'RESET PASS' action.
