FROMGIT: HID: hid-ntrig: Prevent memory leak in ntrig_report_version()

[ Upstream commit 53f731f5bba0cf03b751ccceb98b82fadc9ccd1e ]

Use a scope-based cleanup helper for the buffer allocated with kmalloc()
in ntrig_report_version() to simplify the cleanup logic and prevent
memory leaks (specifically the !hid_is_usb()-case one).
