[PATCH linux-next] serial: drop unneeded assignment

[CGEL]

From: Luo penghao <luo.penghao@xxxxxxxxxx>

The first assignment is not used. In order to keep the code style
consistency of the whole file, the first 'offset' assignment should be
deleted.

The clang_analyzer complains as follows:

drivers/tty/nozomi.c:520:6: warning:
Although the value storedto 'offset' is used in the enclosing expression,
the value is never actually read from 'offset'.
