LoongArch: Remove redundant cmdline parameters when using --reuse-cmdline option

In LoongArch, when using the --reuse-cmdline option to reuse the current
command line, it may lead to redundancy (like kexec, initrd command line
arguments). In order to avoid the possible impact of initrd removal on other
architectures, remove_parameter will be called in a specific architecture
for processing.
