firmware: dmi-id: add a release callback function

Browse Source 
dmi_class uses kfree() as the .release function, but that now causes
a warning with clang-16 as it violates control flow integrity (KCFI)
rules:

drivers/firmware/dmi-id.c:174:17: error: cast from 'void (*)(const void *)' to 'void (*)(struct device *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
  174 |         .dev_release = (void(*)(struct device *)) kfree,

Add an explicit function to call kfree() instead.

Fixes: 4f5c791a85 ("DMI-based module autoloading")
