[PATCH] rxrpc: rxkad: Remove redundant variable offset

[Jiapeng Chong]

Variable offset 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/rxrpc/rxkad.c:579:2: warning: Value stored to 'offset' is never read
[clang-analyzer-deadcode.DeadStores].

net/rxrpc/rxkad.c:485:2: warning: Value stored to 'offset' is never read
[clang-analyzer-deadcode.DeadStores].
