[ Upstream commit 5c455c5ab3 ]
mwifiex_cmd_802_11_ad_hoc_start() 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().

AID gets updated during TDLS setup, but modified value isn't reflected
in "priv->assoc_rsp_buf". This causes TDLS setup failure. The problem is
fixed here.

When an association command is sent to firmware but the process is
killed before the command response arrives, driver will try to
access bss_desc which is already freed. This issue is fixed by
checking return value of bss_start.

Even if ADHOC start or join attempt is failed, these commands
are returned with success status by firmware. Actual connection
result is provided inside command response.
This patch parses the adhoc connection result and resets
connection state variables if connection is not successful.
