crypto: aspeed - Fix check for platform_get_irq() errors
The platform_get_irq() function returns negative on error and
positive non-zero values on success. It never returns zero, but if it
did then treat that as a success.
Also remove redundant dev_err() print as platform_get_irq() already
prints an error.
