When handling FIB events, the rule in post act will not be deleted.
And because the post act rule has packet reformat and modify header
actions, also will hit the following syndromes:
mlx5_core 0000:08:00.0: mlx5_cmd_out_err:829:(pid 11613): DEALLOC_MODIFY_HEADER_CONTEXT(0x941) op_mod(0x0) failed, status bad resource state(0x9), syndrome (0x1ab444), err(-22)
mlx5_core 0000:08:00.0: mlx5_cmd_out_err:829:(pid 11613): DEALLOC_PACKET_REFORMAT_CONTEXT(0x93e) op_mod(0x0) failed, status bad resource state(0x9), syndrome (0x179e84), err(-22)
Fix it by unoffloading post act rule when handling FIB events.

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.
