scsi: lpfc: Fix possible file string name overflow when updating firmware
Because file_name and phba->ModelName are both declared a size 80 bytes,
the extra ".grp" file extension could cause an overflow into file_name.
Define a ELX_FW_NAME_SIZE macro with value 84. 84 incorporates the 4 extra
characters from ".grp". file_name is changed to be declared as a char and
initialized to zeros i.e. null chars.
