x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
From: Raghavendra K T <raghavendra.kt@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.
