Artem Savkov 297fae4d0b Fix NULL pointer dereference in bl_free_device(). ... When bl_parse_deviceid() fails in bl_alloc_deviceid_node() on blkdev_get_by_*() step we get an pnfs_block_dev struct that is uninitialized except for bdev field which is set to whatever error blkdev_get_by_*() returns. bl_free_device() then tries to call blkdev_put() if bdev is not 0 resulting in a wrong pointer dereference. Fixing this by setting bdev in struct pnfs_block_dev only if we didn't get an error from blkdev_get_by_*().
