[PATCH] storage_encryption: silence clang warning

[Eric Blake <eblake@xxxxxxxxxx>]

For printf("%*s",foo,bar), clang complains if foo is not int:

warning: field width should have type 'int', but argument has
type 'unsigned int' [-Wformat]

* src/conf/storage_encryption_conf.c
(virStorageEncryptionSecretFormat, virStorageEncryptionFormat):
Use correct type.
