Subject: [PATCH] caif: Remove redundant variable expectlen

Variable expectlen is being assigned a value from a calculation
however the variable is never read, so this redundant variable
can be removed.

Cleans up the following clang-analyzer warning:

net/caif/cfserl.c:126:5: warning: Value stored to 'expectlen' is never
read [clang-analyzer-deadcode.DeadStores].
