hw/nvme: fix memory leak in nvme_dsm
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:
==3075137==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 480 byte(s) in 6 object(s) allocated from:
