Subject: [PATCH] crypto: ccp: remove unused variable qim

From: Colin Ian King <[email protected]>

Variable qim is assigned but never read, it is redundant and can
be removed.

Cleans up clang warning: Value stored to 'qim' is never read

Fixes: 4b394a232df7 ("crypto: ccp - Let a v5 CCP provide the same function as v3")
