Michael J. Ruhl e3091644bf IB/hfi1: Remove incorrect call to do_interrupt callback 
The general interrupt handler is_rcv_avail_int() has two paths,
do_interrupt() (callback) and handle_user_interrupt().  The
do_interrupt() callback is for the threaded receive handling.
is_rcv_avail_int() cannot handle threaded IRQs.

If the do_interrupt() path is taken, and the IRQ returns
IRQ_WAKE_THREAD, the IRQ behavior will be indeterminate.

Remove incorrect call to do_interrupt() from is_rcv_avail_int(),
leaving the un-threaded (handle_user_interrupt()) path.

Fixes: f4f30031c3 ("staging/rdma/hfi1: Thread the receive interrupt.")
