ACPI: irq: Fix incorrect return value in acpi_register_gsi()
commit 0c21a18d5d6c6a73d098fb9b4701572370942df9 upstream.
acpi_register_gsi() should return a negative value in case of failure.
Currently, it returns the return value from irq_create_fwspec_mapping().
However, irq_create_fwspec_mapping() returns 0 for failure. Fix the
issue by returning -EINVAL if irq_create_fwspec_mapping() returns zero.
