Subject: [PATCH][next] coda: Remove redundant assignments to variable s

Variable s is being assigned values and it is not being read afterwards.
The assignments are redundant and can be removed.

Cleans up 2 clang-scan warnings:
fs/coda/upcall.c:259:9: warning: Value stored to 's' is never read [deadcode.DeadStores]
        s = ( new_length & ~0x3) +4; /* round up to word boundary */
fs/coda/upcall.c:430:9: warning: Value stored to 's' is never read [deadcode.DeadStores]
        s = (len & ~0x3) + 4;
