scsi: hpsa: Replace deprecated strncpy() with strscpy_pad()

strncpy() is deprecated for NUL-terminated destination buffers. Replace
memset() and strncpy() with strscpy_pad() to copy the version string and
fill the remaining bytes in the destination buffer with NUL bytes. This
avoids zeroing the memory before copying the string.

Compile-tested only.
