userspace: don't adjust perms on object init
We got rid of letting uninitialized objects being a free-for-all
and permission to do stuff on an object is now done explicitly.
If a user thread is initializing an object, they will already have
permission on it.
If a supervisor thread is initializing an object, that supervisor
thread may or may not want that object added to its set of object
permissions for purposes of permission inheritance or dropping to
user mode.
Resetting all permissions on initialization makes objects much
harder to share and re-use; for example other threads will lose
access if some thread re-inits a shared semaphore.
For all these reasons, just keep the permissions as they are when
an object is initialized.
We will need some policy for permission reset when objects are
requested and released from pools, but the pool implementation
should take care of that.
