IB: Use DEFINE_SPINLOCK() for static spinlocks
Rather than just defining static spinlock_t variables and then
initializing them later in init functions, simply define them with
DEFINE_SPINLOCK() and remove the calls to spin_lock_init(). This cleans
up the source a tad and also shrinks the compiled code; eg on x86-64:
add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-40 (-40)
function old new delta
ib_uverbs_init 336 326 -10
ib_mad_init_module 147 137 -10
ib_sa_init 123 103 -20
