x86/apic/uv: Remove unnecessary #ifdef

In the file x2apic_uv_x.c, some code is compiled conditionally
depending on CONFIG_SMP. However, the file is only built, if
CONFIG_X86_UV is enabled.

CONFIG_X86_UV depends on CONFIG_NUMA, which itself depends on
CONFIG_SMP, so the #ifdef will always evaluate to true, if the
file is compiled. Thus, it is unnecessary and can be removed.
