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.
