Fix race between dex-file registration and class-loader deletion
We keep track of class-loaders by having a list with jweak references
to the dex-caches. When we register a new dex-file we check that the
dex-cache hasn't already been registered with a different
class-loader. We decoded the jweak and performed this check this
without any locks however meaning we could race with class-loader
cleanup. This could cause CHECK failures as we try to decode a deleted
jweak.
