mwifiex: Fix possible buffer overflows in mwifiex_cmd_append_vsie_tlv()
[ Upstream commit b70261a288ea4d2f4ac7cd04be08a9f0f2de4f4d ]
mwifiex_cmd_append_vsie_tlv() calls memcpy() without checking
the destination size may trigger a buffer overflower,
which a local user could use to cause denial of service
or the execution of arbitrary code.
Fix it by putting the length check before calling memcpy().
