usb: gadget: f_hid: fix error handling in ghid_setup()
There were a two issues here.
1) We returned PTR_ERR(NULL) which means success if class_create()
failed.
2) If alloc_chrdev_region() failed then we should clean up before
returning.
Also kernel style is to have "error handling" as opposed to "success
handling". In the original code checking for "if (!status) " is
confusing and this bad style is what lead to bug #2.
