[Qemu-devel] [PULL v2 19/25] acpi: cleanup bios_linker_loader_cleanup()

["Michael S. Tsirkin" <mst@redhat.com>]

From: Igor Mammedov <imammedo@redhat.com>

bios_linker_loader_cleanup() is called only from one place
and returned value is immediately freed wich makes returning
pointer from bios_linker_loader_cleanup() useless.

Cleanup bios_linker_loader_cleanup() by freeing
data there so that caller won't have to free it.
