net: ll_temac: fix error checking of irq_of_parse_and_map()

Browse source

Most kernel functions return negative error codes but some irq functions
return zero on error.  In this code irq_of_parse_and_map(), returns zero
and platform_get_irq() returns negative error codes.  We need to handle
both cases appropriately.
