I fixed a stringop-overread warning earlier this year, now a
second copy of the original code was added and the warning came
back:

drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_cmf_info_show':
drivers/scsi/lpfc/lpfc_attr.c:289:25: error: 'strnlen' specified bound 4095 exceeds source size 24 [-Werror=stringop-overread]
289 | strnlen(LPFC_INFO_MORE_STR, PAGE_SIZE - 1),
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix it the same way as the other copy.

Fixes: ada48ba70f6b ("scsi: lpfc: Fix gcc -Wstringop-overread warning")
Fixes: 74a7baa2a3ee ("scsi: lpfc: Add cmf_info sysfs entry")
