selinux: keep context struct members in sync
Commit 53f3517ae087 ("selinux: do not leave dangling pointer behind")
reset the `str` field of the `context` struct in an OOM error branch.
In this struct the fields `str` and `len` are coupled and should be kept
in sync. Set the length to zero according to the string be set to NULL.
