MIPS: Delete unused code in linux32.c
The A() & AA() macros have been unused since commit 05e4396651ca ("[MIPS] Use SYSVIPC_COMPAT to fix various problems on N32"), which switched to the more standard compat_ptr(). RLIM_INFINITY32, RESOURCE32() & struct rlimit32 have been present but unused since the beginning of the git era. Remove the dead code.
