Abort the update if there's not enough new data

Right now the update stuck in a deadlock if there's less new data than
expection. Add some checkers and abort the update if such case happens.
Also add a corresponding test.

Bug: 36787146
Test: update aborts correctly on bullhead && recovery_component_test passes
