Subject: [RHEL7.5 PATCH 003/169] Fix oddity where mdadm did not recognise
 a relative path

mdadm assumed that a pathname started with a "/", while an array
name didn't. This alters the logic so that if the first character
is not a "/" it tries to open an array, and if that fails it drops
through to the pathname code rather than terminating immediately
with an error.
