Subject: [PATCH] integrity/security: fix digsig.c build error with header file

From: Randy Dunlap <rdunlap@...radead.org>

security/integrity/digsig.c has build errors on some $ARCH due to a
missing header file, so add it.

  security/integrity/digsig.c:146:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
