x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks

From: Raghavendra K T <raghavendra.kt@xxxxxxxxxxxxxxxxxx>

The code size expands somewhat, and its better to just call
a function rather than inline it.

Thanks Jeremy for original version of ARCH_NOINLINE_SPIN_UNLOCK config patch,
which is simplified.
