net: tipc: resize nlattr array to correct size
[ Upstream commit 44194cb1b6045dea33ae9a0d54fb7e7cd93a2e09 ]
According to nla_parse_nested_deprecated(), the tb[] is supposed to the
destination array with maxtype+1 elements. In current
tipc_nl_media_get() and __tipc_nl_media_set(), a larger array is used
which is unnecessary. This patch resize them to a proper size.
Fixes: 1e55417d8fc6 ("tipc: add media set to new netlink api")
Fixes: 46f15c6794fb ("tipc: add media get/dump to new netlink api")
