tty: xtensa/iss: use strnlen to improve iss_console_write
Use strnlen() to limit scanning 's' to 'count' bytes. Use the length of
's' to decide if simc_write() should be called instead of dereferencing
it first and then calling strlen().
With strnlen(), iss_console_write() is further hardened against callers
where 's' is not NUL-terminated.
