ACPI: pfr_telemetry: Fix info leak in pfrt_log_ioctl()
The "data_info" struct is copied to the user. It has a 4 byte struct
hole after the last struct member so we need to memset that to avoid
copying uninitialized stack data to the user.
Fixes: b0013e037a8b ("ACPI: Introduce Platform Firmware Runtime Telemetry driver")
