fix(misalign): fix misaligned HLV and HLVX

[happy-lx]

In the previous design, the H extension information was lost in the fuOpType of the misalignBuffer split instruction, causing the split instruction to not perform two-stage address translation and cause errors.

This PR fixes the information about H extension in fuOpType in misalignBuffer.
