x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
From: Raghavendra K T <raghavendra...@linux.vnet.ibm.com>
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.

spinlock implementation with something virtualization-friendly
