Zilin Guan 5192620446 pnfs/blocklayout: Fix memory leak in bl_parse_scsi()

[ Upstream commit 5a74af51c3 ]

In bl_parse_scsi(), if the block device length is zero, the function
returns immediately without releasing the file reference obtained via
bl_open_path(), leading to a memory leak.

Fix this by jumping to the out_blkdev_put label to ensure the file
reference is properly released.
