Variable tmout is being assigned a value that is never read, it is
being re-assinged in the following for-loop statement. The assignment
is redundant and can be removed.
Cleans up clang scan warning:
drivers/tty/serial/omap-serial.c:1096:3: warning: Value stored to 'tmout'
is never read [deadcode.DeadStores]
