scsi: lpfc: Use memcpy() for BIOS version

In the Linux kernel, the following vulnerability has been resolved:

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.
