smack: pass error code through pointers
This patch makes the following functions to use ERR_PTR() and related macros to pass the appropriate error code through returned pointers: smk_parse_smack() smk_import_entry() smk_fetch() It also makes all the other functions that use them to handle the error cases properly. This ways correct error codes from places where they happened can be propagated to the user space if necessary. Doing this it fixes a bug in onlycap and unconfined files handling. Previously their content was cleared on any error from smk_import_entry/smk_parse_smack, be it EINVAL (as originally intended) or ENOMEM. Right now it only reacts on EINVAL passing other codes properly to userspace. Comments have been updated accordingly. Signed-off-by: Lukasz Pawelczyk <l.pawelczyk@samsung.com>
