crypto: hisilicon/sec2 - fix for aead invalid authsize

Browse source

[ Upstream commit a5a9d95993 ]

When the digest alg is HMAC-SHAx or another, the authsize may be less
than 4 bytes and mac_len of the BD is set to zero, the hardware considers
it a BD configuration error and reports a ras error, so the sec driver
needs to switch to software calculation in this case, this patch add a
check for it and remove unnecessary check that has been done by crypto.
