scsi: lpfc: Use memcpy() for BIOS version

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 of 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.
