Eric Dumazet de5e2ddf9b ipmi: proper spinlock initialization 
Unloading ipmi module can trigger following error.  (if
CONFIG_DEBUG_SPINLOCK=y)

[ 9633.779590] BUG: spinlock bad magic on CPU#1, rmmod/7170

Fix this by initializing spinlocks in a smi_info_alloc() helper function,
right after memory allocation and clearing.
