LoongArch: Fix copy_thread() build errors
Commit c5febea0956fd387 ("fork: Pass struct kernel_clone_args into copy_thread") change the prototype of copy_thread(), while commit 5bd2e97c868a8a44 ("fork: Generalize PF_IO_WORKER handling") change the structure of kernel_clone_args. They cause build errors, so fix it. Fixes: 5bd2e97c868a8a44 ("fork: Generalize PF_IO_WORKER handling") Fixes: c5febea0956fd387 ("fork: Pass struct kernel_clone_args into copy_thread") Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
