Johan Hovold 433b7cd1e7 firmware: qemu_fw_cfg: fix sysfs information leak 
Make sure to always NUL-terminate file names retrieved from the firmware
to avoid accessing data beyond the entry slab buffer and exposing it
through sysfs in case the firmware data is corrupt.

Fixes: 75f3e8e47f ("firmware: introduce sysfs driver for QEMU's fw_cfg device")
