From: Randy Dunlap <rdunlap@infradead.org>

Fix 30 warnings for missing "struct inode" declaration (like these) by
adding a forward reference for it.
These warnings come from 'headers_check' (CONFIG_HEADERS_CHECK):
  CC      include/trace/events/iomap.h.s

./../include/trace/events/iomap.h:49:18: warning: 'struct inode' declared inside \
                parameter list will not be visible outside of this definition or \
                declaration
./../include/trace/events/iomap.h:77:18: warning: 'struct inode' declared inside \
parameter list will not be visible outside of this definition or declaration
