[PATCH][next] tty: serial: jsm: remove redundant assignments of several variables

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Several variables are being assigned with values that are never
read and being updated later with a new value. The initializations
are redundant and can be removed.

Addresses-Coverity: ("Unused value")
