scsi: storvsc: fix memory leak on ring buffer busy
commit 0208eeaa650c5c866a3242201678a19e6dc4a14e upstream.
When storvsc is sending I/O to Hyper-v, it may allocate a bigger buffer
descriptor for large data payload that can't fit into a pre-allocated
buffer descriptor. This bigger buffer is freed on return path.
If I/O request to Hyper-v fails due to ring buffer busy, the storvsc
allocated buffer descriptor should also be freed.
[mkp: applied by hand]
Fixes: be0cf6ca301c ("scsi: storvsc: Set the tablesize based on the information given by the host")
