[PATCH -next] integrity: Remove set but not used variable 'acl'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

security/integrity/digsig.c: In function 'integrity_init_keyring':
security/integrity/digsig.c:99:18: warning:
 variable 'acl' set but not used [-Wunused-but-set-variable]

It seems 'acl' is needed in __integrity_init_keyring

Fixes: 6100ac53909d ("keys: Replace uid/gid/perm permissions checking with an ACL")
