Mickaël Salaün 86dc969314 selinux: fix lsm_get_self_attr()
selinux_getselfattr() doesn't properly initialize the string pointer
it passes to selinux_lsm_getattr() which can cause a problem when an
attribute hasn't been explicitly set; selinux_lsm_getattr() returns
0/success, but does not set or initialize the string label/attribute.
Failure to properly initialize the string causes problems later in
selinux_getselfattr() when the function attempts to kfree() the
string.
