[PATCH -next 1/2] tsnep: fix resource_size.cocci warnings

Use resource_size function on resource object
instead of explicit computation.

Clean up coccicheck warning:
./drivers/net/ethernet/engleder/tsnep_main.c:1155:21-24: ERROR: Missing
resource_size with io

Remove .owner field if calls are used which set it automatically

Eliminate the following coccicheck warning:
./drivers/net/ethernet/engleder/tsnep_main.c:1263:3-8: No need to set
.owner here. The core will do it.

In fact adapter->size can be removed completely, because it is used nowhere.
I will submit a patch.

Applied this one and took Gerhard's patch for the resource size thing.
Thanks!
