[PATCH 1/2] mailbox: qcom-ipcc: amend qcom_ipcc_domain_map() to report errors

[Gabriele Paoloni <gpaoloni@redhat.com>]

Currently qcom_ipcc_domain_map() ignores errors returned by
irq_set_chip_data() and invokes irq_set_chip_and_handler()
that in turn ignores errors returned by irq_set_chip().
This patch fixes both issues; no other functional changes
are implemented.
