um: Re-evaluate thread flags repeatedly

Browse source

[ Upstream commit b9e2f2246e ]

The thread flags may change during their processing.
For example a task_work can queue a new signal to be sent.
This signal should be delivered before returning to usespace again.

Evaluate the flags repeatedly similar to other architectures.
