staging: r8712u: Fix regression caused by commit 8c213fa
commit 2080913e017ab9f88379d93fd09546ad95faf87b upstream. In commit 8c213fa "staging: r8712u: Use asynchronous firmware loading", the command to release the firmware was placed in the wrong routine. In combination with the bug introduced in commit a5ee652 "staging: r8712u: Interface-state not fully tracked", the driver attempts to upload firmware that had already been released. This bug is the source of one of the problems in https://bugs.archlinux.org/task/27996#comment89833.
