[PATCH 1/2] ib/ehca: Do not turn off irqs in tasklet context

[Alexander Schmidt]

The irq_spinlock is only taken in tasklet context, so it is safe not to
disable hardware interrupts.

[PATCH 2/2] ib/ehca: allow access for ib_query_qp()

[Alexander Schmidt]

The max_dest_rd_atomic and max_qp_rd_atomic values are
properly returned by query_qp(), so there should not be
an error returned when they are queried.
