libbinder: restartWrite abort out of memory

Most code in Android and indeed in libbinder will
abort in this case. Since setData is underspecified,
we should probably start the process of removing all
the users of it (AIDL does not use it). However,
until it can be removed, it's safer to abort here
than risk mObjects is referenced in an invalid state
from here on.
