cmd/internal/obj/loong64: fix the usage of offset in the instructions [X]VLDREPL.{B/H/W/D}

The previously defined usage of offset was ambiguous and not easy to understand.
For example, to fetch 4 bytes of data from the address base+8 and
broadcast it to each word element of vector register V5, the assembly
implementation is as follows:
	previous: VMOVQ 2(base), V5.W4
	current:  VMOVQ 8(base), V5.W4
