Chenghao Duan e7a7d7e629 LoongArch: BPF: Enhance the bpf_arch_text_poke() function 
commit 73721d8676 upstream.

Enhance the bpf_arch_text_poke() function to enable accurate location
of BPF program entry points.

When modifying the entry point of a BPF program, skip the "move t0, ra"
instruction to ensure the correct logic and copy of the jump address.
