firmware: dmi-sysfs: Remove "dmi" directory on module exit
With CONFIG_DEBUG_KOBJECT_RELEASE=y, removing and immediately reloading the
dmi-sysfs module causes the following warning:
sysfs: cannot create duplicate filename '/firmware/dmi'
kobject_add_internal failed for dmi with -EEXIST, don't try to register things with the same name in the same directory.
The "dmi" directory stays in sysfs until the dmi_kobj is released, and
DEBUG_KOBJECT_RELEASE delays that.
I don't think we can hit this problem in normal usage because dmi_kobj is
static and nothing outside dmi-sysfs can get a reference to it, so the
only way to delay the "dmi" release is with DEBUG_KOBJECT_RELEASE.
