pnfs/flexfiles: Fix memory leak in nfs4_ff_alloc_deviceid_node()

Browse source

[ Upstream commit 0c72808365 ]

In nfs4_ff_alloc_deviceid_node(), if the allocation for ds_versions fails,
the function jumps to the out_scratch label without freeing the already
allocated dsaddrs list, leading to a memory leak.

Fix this by jumping to the out_err_drain_dsaddrs label, which properly
frees the dsaddrs list before cleaning up other resources.
