of: irq: Report individual failures in of_irq_init()
New pr_err(), a copy of preceeding pr_debug(), faciliates debugging. This change was inspired by a long lasting debugging of the octeon_irq_init_ciu() which fails completely silently and leaves the interrupt controller half-way configured which in turn had very non-obvious effects.
