RDMA/nes: Free IRQ before killing tasklet

commit: 4cd1e5eb3cbe6e0cc934959770b4c60eac6ecf66

Move the free_irq() call in nes_remove() to before the tasklet_kill();
otherwise there is a window after tasklet_kill() where a new interrupt
can be handled and reschedule the tasklet, leading to a use-after-free
crash.
