[PATCH AUTOSEL 5.7 167/274] Crypto/chcr: fix for ccm(aes) failed test

From: Devulapally Shiva Krishna <redacted>

[ Upstream commit 10b0c75d7bc19606fa9a62c8ab9180e95c0e0385 ]

The ccm(aes) test fails when req->assoclen > ~240bytes.

The problem is the value assigned to auth_offset is wrong.
As auth_offset is unsigned char, it can take max value as 255.
So fix it by making it unsigned int.
