Subject: [PATCH] amd64-agp: remove redundant assignment to variable i

Variable i is being assigned a value that is never read, it is being
re-assigned later in a for-loop. The assignment is redundant and can
be removed.

Cleans up clang scan build warning:
drivers/char/agp/amd64-agp.c:336:2: warning: Value stored to 'i' is
never read [deadcode.DeadStores]
