[PATCH v2 09/12] raw/ifpga: reset FD in interrupt handle

[David Marchand]

The interrupt handle fd points to efd[0] which is already closed
by rte_intr_efd_disable(). Clear the FD reference before freeing
the interrupt handle to avoid a spurious leak warning.

Fixes: d770ee9caed0 ("interrupts: warn on leaked FDs")
