CVE-2026-72128

In the Linux kernel, the following vulnerability has been resolved:

nvmet: fix refcount leak in nvmet_sq_create()

In nvmet_sq_create(), a reference on the ctrl is taken
via kref_get_unless_zero() before calling nvmet_check_sqid().
If nvmet_check_sqid() fails, the function returns the error
directly without releasing the reference, leading to a leak.

Fix this by jumping to the "ctrl_put" label, which already
performs the necessary nvmet_ctrl_put(ctrl). This ensures the
reference is properly released on this error path.
