[PATCH v2 2/3] configfs: Do not override creating attribute file failure in populate_attrs()

[Zijun Hu]

From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>

populate_attrs() may override failure for creating attribute files
by success for creating subsequent bin attribute files, and have
wrong return value.

Fix by creating bin attribute files under successfully creating
attribute files.
