staging: ccree: NULLify backup_info when unused

Browse source

commit 46df882498 upstream.

backup_info field is only allocated for decrypt code path.
The field was not nullified when not used causing a kfree
in an error handling path to attempt to free random
addresses as uncovered in stress testing.
