Subject: LoongArch/tlb: fix "error: parameter 'ptep' set but not used" due to __tlb_remove_tlb_entry()

With LLVM=1 and W=1 we get:
./include/asm-generic/tlb.h:629:10: error: parameter 'ptep' set
but not used [-Werror,-Wunused-but-set-parameter]
We fixed a similar issue via Arnd in the introducing commit, missed the
loongarch variant. Turns out, there is no need for loongarch to have a
custom variant, so let's just drop it and rely on the asm-generic one.
