[PATCH v2 6/6] fwu: print a message if empty capsule checks fail

[Sughosh Ganu]

When dealing with processing of the empty capsule, the capsule gets
applied only when the checks for the empty capsule pass. Print a
message to highlight if empty capsule checks fail, and return an error
value, similar to the normal capsules.
