drivers/net: Correct use of request_region/request_mem_region 

request_mem_region should be used with release_mem_region, not request_region.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/

)

// <smpl>
@r2@
expression start;

request_mem_region(start,...)

@b2@
expression r2.start;

request_region(start,...)

@depends on !b2@
expression r2.start;
expression E;

- release_region
+ release_mem_region
  (start,E)
// </smpl>
