Shay Drory def4cd43f5 IB/umad: Return EPOLLERR in case of when device disassociated 
Currently, polling a umad device will always works, even if the device was
disassociated. A disassociated device should immediately return EPOLLERR
from poll(). Otherwise userspace is endlessly hung on poll() with no idea
that the device has been removed from the system.
