LoongArch: Use unsigned long for _end and _text
commit a258a3cb1895e3acf5f2fe245d17426e894bc935 upstream.
It is better to use unsigned long rather than long for _end and _text to
calculate the kernel length.
Cc: stable@vger.kernel.org # v6.3+
Fixes: e5f02b51fa0c ("LoongArch: Add support for kernel address space layout randomization (KASLR)")
