From: Zheyu Ma <zheyum...@gmail.com>
The allocated memory to hold LBA ranges leaks in the nvme_dsm function. This
happens because the allocated memory for iocb->range is not freed in all
error handling paths.
Fix this by adding a free to ensure that the allocated memory is properly freed.
ASAN log:
