[PATCH -mm] crypto: scatterwalk.h needs sched.h

[Randy Dunlap <randy.dunlap@oracle.com>]

From: Randy Dunlap <randy.dunlap@oracle.com>

When CONFIG_PREEMPT_NONE=y, scatterwalk.h still uses cond_resched()
so it needs to include sched.h:

linux-2.6.24-rc6-mm1/include/crypto/scatterwalk.h:52: error: implicit declaration of function 'cond_resched'
make[2]: *** [crypto/digest.o] Error 1
