net: ibm: emac: fix unchecked platform_get_irq return value

platform_get_irq() returns a negative errno on failure.
Commit a598f66d9169 replaced irq_of_parse_and_map() (which returns 0
on failure) with platform_get_irq() but dropped the error check.
Without it, a negative IRQ number is passed to devm_request_irq(),
which fails with -EINVAL instead of propagating the real error
from platform_get_irq().

Add the missing error check and goto err_gone.
