The function “platform_get_irq” can log an error already.
Thus omit a redundant message for the exception handling in the
calling function.
It looks to me that not all error path of platform_get_irq() were loggd.
And git grep told me there're other users of platform_get_irq() that
check and log by themselves.
Thanks
