Subject: [PATCH 1/2] ARM64 / ACPI: Ignore the return error value of acpi_map_gic_cpu_interface()

MADT table scannig will stopped once it gets the errors
returned by the handler, which is acpi_map_gic_cpu_interface()
in for ARM64, so Ignore the return error value to search for
all enabled CPUs for SMP init.
