When the ENA device resets to recover from some error state, all LLQ configuration values are reset to their defaults, because LLQ is initialized only once during ena_probe(). Changes in this commit: 1. Move the LLQ configuration process into ena_init_device() which is called from both ena_probe() and ena_restore_device(). This way, LLQ setup configurations that are different from the default values will survive resets. 2. Extract the LLQ bar mapping to ena_map_llq_bar(), and call once in the lifetime of the driver from ena_probe(), since there is no need to unmap and map the LLQ bar again every reset. 3. Map the LLQ bar if it exists, regardless if initialization of LLQ placement policy (ENA_ADMIN_PLACEMENT_POLICY_DEV) succeeded or not. Initialization might fail the first time, falling back to the ENA_ADMIN_PLACEMENT_POLICY_HOST placement policy, but later succeed after device reset, in which case the LLQ bar needs to be mapped already.

README
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.
