CVE-2024-27392

In the Linux kernel, the following vulnerability has been resolved: nvme:
host: fix double-free of struct nvme_id_ns in ns_update_nuse() When
nvme_identify_ns() fails, it frees the pointer to the struct nvme_id_ns
before it returns. However, ns_update_nuse() calls kfree() for the pointer
even when nvme_identify_ns() fails. This results in KASAN double-free,
which was observed with blktests nvme/045 with proposed patches [1] on the
kernel v6.8-rc7. Fix the double-free by skipping kfree() when
nvme_identify_ns() fails.
