x86/uv: Fix uninitialized spinlocks
commit d2ebc71d472020bc30e29afe8c4d2a85a5b41f56 upstream.
Initialize two spinlocks in tlb_uv.c and also properly define/initialize
the uv_irq_lock.
The lack of explicit initialization seems to be functionally
harmless, but it is diagnosed when these are turned on:
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_MUTEXES=y
CONFIG_DEBUG_LOCK_ALLOC=y
CONFIG_LOCKDEP=y
