net/smc: check v2_ext_offset/eid_cnt/ism_gid_cnt when receiving proposal msg
When receiving proposal msg in server, the fields v2_ext_offset/
eid_cnt/ism_gid_cnt in proposal msg are from the remote client
and can not be fully trusted. Especially the field v2_ext_offset,
once exceed the max value, there has the chance to access wrong
address, and crash may happen.
This patch checks the fields v2_ext_offset/eid_cnt/ism_gid_cnt
before using them.
Fixes: 8c3dca341aea ("net/smc: build and send V2 CLC proposal")
