platform/x86: thinkpad_acpi: remove redundant assignment to variable i

The variable i is being initialized with the value 0 that is never
read, it is being re-assigned 0 again in a for-loop statement later
on. The initialization is redundant and can be removed.

The initialization of variable n can also be deferred after the
sanity check on pointer n and the declaration of all the int variables
can be combined as a final code clear-up.

Cleans up clang scan build warning:
warning: Value stored to 'i' is never read [deadcode.DeadStores]
