MIPS: Remove unused sys_32_mmap2

The sys_32_mmap2 function has been unused since we started using syscall
wrappers in commit dbda6ac08976 ("MIPS: CVE-2009-0029: Enable syscall
wrappers."), and is indeed identical to the sys_mips_mmap2 function that
replaced it in sys32_call_table.

Remove the dead code.
