Subject: [PATCH 2/2] staging: r8712u: Fix regression caused by commit 8c213fa

In commit 8c213fa, the command to release the firmware was placed
in the wrong routine. With NetworkManager, problems were rare, but
when using wicd as the network control, there is a problem as shown
in https://bugs.archlinux.org/task/27996#comment89833.
