X-Git-Tag: firefly_0821_release~16477^2^2~14

capabilities: define get_vfs_caps_from_disk when file caps are not enabled

When CONFIG_SECURITY_FILE_CAPABILITIES is not set the audit system may
try to call into the capabilities function vfs_cap_from_file.  This
patch defines that function so kernels can build and work.
