Xu Rao 9977321835 thunderbolt: Fix bandwidth group reservation indexing ...

commit d2ee4d47aa upstream.

Valid bandwidth group IDs range from 1 through MAX_GROUPS, while Group
ID 0 is reserved. tb_consumed_dp_bandwidth() uses the Group ID directly
to index its local group_reserved[] array.

The array currently has MAX_GROUPS entries, so its valid indices are 0
through MAX_GROUPS - 1. Group ID MAX_GROUPS therefore accesses one
element past the end, and the final group's reserved bandwidth is not
included when the array is summed.

Give group_reserved[] MAX_GROUPS + 1 entries so direct Group ID
indexing covers the reserved ID 0 and valid IDs 1 through MAX_GROUPS.

Fixes: 52a4490e89 ("thunderbolt: Reserve released DisplayPort bandwidth for a group for 10 seconds")
