drivers/tty: remove redundant assignment to variable i and rename it to ret

Browse Source 
The variable i is being assigned a value that is never read
and it is being updated later with a new value. The assignment
is redundant and can be removed.  Also rename i to ret as this new
name makes makes more sense.

Addresses-Coverity: ("Unused value")
