Fix Password entry won't enable when lockout finished in screen-off

CL [1] introduced a check to see if password entry need to show
soft-keyboard for fixing keyboard popup unexpected issue.

But it shouldn't need to block the password entry re-enable when
lockout finished in screen-off state.

Move the original check right before the showSoftInput to fix the case.
