staging: rtl8192u: rework init and exit function
The init and exit functions are not releasing resource properly. An error
can be observed when we load/unload/load r8192u_usb module due to this
issue. This patch rework init and exit functions to do proper resource
release on init error and module unload.
The __exit attribute is stripped from some functions since they are now
being used by module init functions.
