blk-crypto-fallback does not support wrapped keys, hence
prevent falling back when program_key fails. Add 'is_hw_wrapped'
flag to blk-crypto-key to mention if the key is wrapped
when the key is initialized.
Bug: 147209885
Test: Validate FBE, simulate a failure in the underlying blk
device and ensure the call fails without falling back
to blk-crypto-fallback.
