dev_err call to avoid redundant error message.

70513e1d65 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.

dc377e013b crypto: aspeed - fix return value check in aspeed_hace_probe()
In case of error, the function devm_ioremap_resource() returns
ERR_PTR() not NULL. The NULL test in the return value check must be
replaced with IS_ERR().
