ipmi: avoid gcc warning

A new harmless warning has come up on ARM builds with gcc-4.9:

drivers/char/ipmi/ipmi_msghandler.c: In function 'smi_send.isra.11':
include/linux/spinlock.h:372:95: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized]
  raw_spin_unlock_irqrestore(&lock->rlock, flags);
                                                                                               ^
drivers/char/ipmi/ipmi_msghandler.c:1490:16: note: 'flags' was declared here
  unsigned long flags;
                ^

This could be worked around by initializing the 'flags' variable, but it
seems better to rework the code to avoid this.
