MIPS: Loongson64: Replace deprecated strcpy() with strscpy_pad()

strcpy() is deprecated; use strscpy_pad() instead.

strscpy_pad() already copies the source strings and zero-pads the tail
of the destination buffers, making the explicit initializations to zero
redundant. Remove them to ensure the buffers are only written to once.

No functional changes intended.
