[ Upstream commitb4047aac4e] In some cases, the device is not initialized because reset failed. If another task calls hns3_reset_notify_up_enet() before reset retry, it will cause an error since uninitialized pointer access. So add check for HNS3_NIC_STATE_INITED before calling hns3_nic_net_open() in hns3_reset_notify_up_enet().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
