[Buildroot] [PATCH] package/wpa_supplicant: add upstream 2021-1 security fix

[Peter Korsgaard <peter@korsgaard.com>]

 > Fixes the following security issue:

 > A vulnerability was discovered in how wpa_supplicant processes P2P
 > (Wi-Fi Direct) provision discovery requests. Under a corner case
 > condition, an invalid Provision Discovery Request frame could end up
 > reaching a state where the oldest peer entry needs to be removed. With
 > a suitably constructed invalid frame, this could result in use
 > (read+write) of freed memory. This can result in an attacker within
 > radio range of the device running P2P discovery being able to cause
 > unexpected behavior, including termination of the wpa_supplicant process
 > and potentially code execution.

 > For more details, see the advisory:

Committed to 2020.02.x and 2020.11.x, thanks.
