MIPS: Netlogic: Fix oprofile compile on XLR uniprocessor 

The commit c783390a0e [MIPS: oprofile:
Support for XLR/XLS processors] causes a compilation failure when
oprofile is enabled and SMP is not configured.

arch/mips/oprofile/op_model_mipsxx.c: In function 'mipsxx_cpu_setup':
arch/mips/oprofile/op_model_mipsxx.c:181:2: error: implicit declaration of function 'cpu_logical_map'

To fix this, update oprofile_skip_cpu to not call cpu_logical_map when
CONFIG_SMP is not defined.
