qlcnic: Restructuring of qlc_83xx_fw_info structure.

o Removed unused and unnecessary members from qlc_83xx_fw_info
  structure.
o Made fw_info member of qlcnic_hardware_context as a pointer to
  qlc_83xx_fw_info structure.
o Added a member fw_file_name to qlc_83xx_fw_info structure which
  will hold the name of firmware image file name.
