This commit fixes the following warning when building virtio_snd driver.
"
*** CID 1583619: Uninitialized variables (UNINIT)
sound/virtio/virtio_kctl.c:294 in virtsnd_kctl_tlv_op()
288
289 break;
290 }
291
292 kfree(tlv);
293
vvv CID 1583619: Uninitialized variables (UNINIT)
vvv Using uninitialized value "rc".
294 return rc;
295 }
296
297 /**
298 * virtsnd_kctl_get_enum_items() - Query items for the ENUMERATED element type.
299 * @snd: VirtIO sound device.
"
This warning is caused by the absence of the "default" branch in the
switch-block, and is a false positive because the kernel calls
virtsnd_kctl_tlv_op() only with values for op_flag processed in
this block.
Also, this commit unifies the cleanup path for all possible control
paths in the callback function.
