[PATCH] scsi: elx: efct: Fix IO leak on unsupported additional CDB

[Haoxiang Li]

efct_dispatch_fcp_cmd() allocates an efct_io before dispatching an
unsolicited FCP command. If the command has an unsupported additional
CDB, the function returns -EIO before handing the IO to the SCSI layer.

Free the allocated IO before returning from this error path.
