cmd: optee: fix hello subcommand argument check
When the `optee hello' subcommand is called, the do_optee_hello_world_ta() function passes a NULL pointer to the strcmp() function while verifying its input argument, which results in the following crash: => optee hello "Synchronous Abort" handler, esr 0x96000010, far 0x0 Fix this by verifying the number of input arguments instead.
