[OEM-5.14/5.17/6.0][PATCH] CVE-2022-47520

[Yuxuan Luo]

[Impact]
There exists an unchecked index in the wilc1000 driver that could trigger an
out-of-bound read vulnerability, damaging system's integrity and
confidentiality for microchip wilc1000 users.

[Backport]
It is a clean cherry for these three OEMs.

[Test]
Due to lack of hardware, all the patches were only compile tested.

[Potential Regression]
The scope of regression is limited to wilc1000/hif.c (or wilc1000/wilc_hif.c
before the refactoring), affected users are wilc1000 users.
