xfs: invalidate cached acl if set via ioctl
Setting or removing the "SGI_ACL_[FILE|DEFAULT]" attributes via the XFS_IOC_ATTRMULTI_BY_HANDLE ioctl completely bypasses the POSIX ACL infrastructure, like setting the "trusted.SGI_ACL_[FILE|DEFAULT]" xattrs did until commit 6caa1056. Similar to that commit, invalidate cached acls when setting/removing them via the ioctl as well.
