scsi: lpfc: Replace strlcat() with seq_buf in lpfc_info()

Browse source

In preparation for removing the strlcat() API[1], replace its uses in
lpfc_info().

The function accumulates a variable number of optional fragments, which
is what seq_buf is for. The intermediate tmp buffer and the per fragment
overflow checks become unnecessary. seq_buf is memory safe by
construction and silently truncates in the same way as the replaced
pattern.

The old code passed phba->ModelDesc as the format string of the first
scnprintf() call. The model description comes from adapter VPD data.
seq_buf_printf() takes a format string, so the replacement prints it
through "%s". A model description containing conversion specifiers is no
longer interpreted.
