mapped in userspace. Add a flag to avoid
doing this for rotator which does not need
userspace mapping.

It is possible to use this object from multiple threads
and there could be a race between a failure in one thread
and another method call from a different thread which would
result in system calls being called with an invalid fd.

Several ioctl calls were returning -1 instead of -errno,
which may confuse upper layers, especially when the error
is -ENOMEM. Also move some existing "err = -errno" calls
to the top of if statements so that errno cannot change
by libc calls in the error handling code.
