Variable tmp is being assigned a value that is never read, the variable
is redundant and can be removed.
Cleans up clang scan build warning:
drivers/rapidio/rio-scan.c:561:10: warning: Although the value stored
to 'tmp' is used in the enclosing expression, the value is never actually
read from 'tmp' [deadcode.DeadStores]
