drivers:net: delete premature free_irq

Free_irq is not needed if there has been no request_irq.  Free_irq is
removed from both the probe and remove functions.  The correct request_irq
and free_irq are found in the open and close functions.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e;
@@

*e = platform_get_irq(...);
... when != request_irq(e,...)
*free_irq(e,...)
// </smpl>
