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.
Fixes: e3cf80fbe02d ("cmd: Add support for optee commands")
