x86/qspinlock-paravirt: Fix missing-prototype warning
__pv_queued_spin_unlock_slowpath() is defined in a header file as
a global function, and designed to be called from inline asm, but
there is no prototype visible in the definition:
kernel/locking/qspinlock_paravirt.h:493:1: error: no previous \
prototype for '__pv_queued_spin_unlock_slowpath' [-Werror=missing-prototypes]
Add this to the x86 header that contains the inline asm calling it,
and ensure this gets included before the definition, rather than
after it.
