Subject: [PATCH 3/3] Input: turbografx - store object in correct index

The variable i is used to check the port to attach to and we are
supposed to save the reference of struct tgfx in the location given by
tgfx_base[i]. But after finding out the index i is getting modified again
so we saved in a wrong index.

Fixes: 4de27a638a99 ("Input: turbografx - use parallel port device model")
