ata: libahci_platform: fix IRQ check
[ Upstream commit b30d0040f06159de97ad9c0b1536f47250719d7d ]
Iff platform_get_irq() returns 0, ahci_platform_init_host() would return 0
early (as if the call was successful). Override IRQ0 with -EINVAL instead
as the 'libata' regards 0 as "no IRQ" (thus polling) anyway...
Fixes: c034640a32f8 ("ata: libahci: properly propagate return value of platform_get_irq()")
