net/smc: check iparea_offset and ipv6_prefixes_cnt when receiving proposal msg
When receiving proposal msg in server, the field iparea_offset
and the field ipv6_prefixes_cnt in proposal msg are from the
remote client and can not be fully trusted. Especially the
field iparea_offset, once exceed the max value, there has the
chance to access wrong address, and crash may happen.
This patch checks iparea_offset and ipv6_prefixes_cnt before using them.
