[libgpiod][PATCH v2 2/2] bindings: python: fix line request by name with multiple entries

[Chuang Zhu <chuang+git@melty.land>]

From: Chuang Zhu <git@chuang.cz>

When multiple entries are requested using line names in
Chip.request_lines, only the the last entry is added to
LineRequest._name_map, causing a ValueError when trying to use functions
like LineRequest.set_value on any former entries.

This patch fixes that by moving the required variables to the correct
scope.
