include/linux/bio.h: use a static inline function for bio_integrity_clone() 



When CONFIG_BLK_DEV_INTEGRITY is not set, we get these warnings:

drivers/md/dm.c: In function 'split_bvec':
drivers/md/dm.c:1061:3: warning: statement with no effect
drivers/md/dm.c: In function 'clone_bio':
drivers/md/dm.c:1088:3: warning: statement with no effect
