selinux: fix error codes in cond_read_av_list()

After this patch cond_read_av_list() no longer returns -1 for any
errors.  It just propagates error code back from lower levels.  Those can
either be -EINVAL or -ENOMEM.

I also modified cond_insertf() since cond_read_av_list() passes that as a
function pointer to avtab_read_item().  It isn't used anywhere else.
