MIPS: VDSO: Prevent use of smp_processor_id()
VDSO code should not be using smp_processor_id(), since it is executed
in user mode.
Introduce a VDSO-specific path which will cause a compile-time
or link-time error (depending upon support for __compiletime_error) if
the VDSO ever incorrectly attempts to use smp_processor_id().
[Matt Redfearn <matt.redfearn@imgtec.com>: Move before change to
smp_processor_id in series]
