ACPI/IORT: Fix memory leak in iort_rmr_alloc_sids()

Browse source

commit f3ef711092 upstream.

If krealloc_array() fails in iort_rmr_alloc_sids(), the function returns
NULL but does not free the original 'sids' allocation. This results in a
memory leak since the caller overwrites the original pointer with the
NULL return value.
