Guanghui Feng 003e6b56d7 ACPI/IORT: Remove erroneous id_count check in iort_node_get_rmr_info()
According to the ARM IORT specifications DEN 0049 issue E,
the "Number of IDs" field in the ID mapping format reports
the number of IDs in the mapping range minus one.

In iort_node_get_rmr_info(), we erroneously skip ID mappings
whose "Number of IDs" equal to 0, resulting in valid mapping
nodes with a single ID to map being skipped, which is wrong.

Fix iort_node_get_rmr_info() by removing the bogus id_count
check.

Fixes: 491cf4a673 ("ACPI/IORT: Add support to retrieve IORT RMR reserved regions")
