Before applying this patchset, when searching for the last element of
smb2_error_map_table array and calling smb2_print_status(),
3480 comparisons are needed.

After applying this patchset, only 10 comparisons are required.

  smb: add two elements to smb2_error_map_table array
  smb/client: sort smb2_error_map_table array
  smb/client: use bsearch() to find target status code
  smb/client: introduce smb2_get_err_map()
  smb/client: introduce smb2maperror KUnit tests
