scsi: lpfc: Fix possible file string name overflow when updating firmware

Browse source

[ Upstream commit f5779b5292 ]

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.
