IB/hfi1: Move URGENT IRQ enable to hfi1_rcvctrl()
User contexts use the receive URGENT interrupt. However, enabling
the IRQ SRC in the file_ops module is not as clean as it could be.
Augment the _rcvctl() function to be able to enable/disable the IRQ
source.
Use the new interface from file_ops to enable/disable the IRQ.
