drivers/net: Correct use of request_region/request_mem_region

Browse source 
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>

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>
