Subject: [PATCH][next] mtd: cfi_cmdset_0002: remove redundant assignment to variable ret

Variable ret is being assigned a value that is never read, the following
goto statement jumps to a statement that assigns ret a return from the
call to function do_write_oneword_once. The assignment is redundant
and can be removed.
