if_open() calls try_module_get(), and after an attempt to lock a mutex the if_open() function may return -ERESTARTSYS without putting the module. Then, when if_open() is executed again, try_module_get() is called making the reference counter of THIS_MODULE greater than one at successful exit from if_open(). The if_close() function puts the module only once, and as a result it can't be unloaded. This patch adds module_put call before the return from if_open().
