[PATCH] lpfc: use memcpy for bios version

[Daniel Wagner]

The strlcat with FORTIFY support is triggering a panic because it thinks
the target buffer will overflow although the correct target buffer
size is passed in.

Anyway, instead memset with 0 followed by a strlcat, just use memcpy and
ensure that the resulting buffer is NULL terminated.

BIOSVersion is only used for the lpfc_printf_log which expects a
properly terminated string.
