MIPS: Fix inconsistancy of __NR_Linux_syscalls value

Originally, __NR_O32_Linux_syscalls, __NR_N32_Linux_syscalls and
__NR_64_Linux_syscalls have the same values as __NR_Linux_syscalls in
corresponding ABIs. But after commit 367f0b50 (MIPS: Wire up
renameat2 syscall) they are not the same. I think this is incorrect and
need a fix.
